Title: New antitumoral compounds

Description:
FIELD OF THE INVENTION  
      The present invention is directed to new kahalalide antitumoral compounds, in particular to analogues of kahalalide F, pharmaceutical compositions containing them and their use as antitumoral, antiviral, antifungal agents and in the treatment of psoriasis.  
     BACKGROUND OF THE INVENTION  
      The kahalalide compounds are peptides isolated from a Hawaiian herbivorous marine species of mollusc,  Elysia rufescens  and its diet, the green alga  Bryopsis  sp. Kahalalide F is described in Hamann, M et al., J. Am. Chem. Soc., 1993, 115, 5825-5826.  
      Kahalalide A-G are described in Hamann, M. et al., J. Org. Chem, 1996, 61, 6594-6600: “Kahalalides: bioactive peptides from a marine mollusk  Elysia rufescens  and its algal diet  Bryopsis  sp.”.  
      Kahalalide H and J are described in Scheuer P. J. et al., J. Nat. Prod. 1997, 60, 562-567: “Two acyclic kahalalides from the sacoglossan mollusk  Elysia rufescens”.    
      Kahalalide O is described in Scheuer P. J. et al., J. Nat. Prod. 2000, 63(1) 152-4: “A new depsipeptide from the sacoglossan mollusk  Elysia ornata  and the green alga  Bryopsis  species”.  
      For kahalalide K, see Kan, Y. et al., J. Nat. Prod. 1999 62(8) 1169-72: “Kahalalide K: A new cyclic depsipeptide from the hawaiian green alga  Bryopsis  species”.

Ecol. 2001, 27(1-1), 2287-99: “Chemical-defenses of the sarcoglossan mollusk  Elysia rufescens  and its host Alga  bryopsis  sp.”.  
      Of the kahalalide compounds, kahalalide F is the most promising because of its antitumoral activity. Its structure is complex, comprising six amino acids as a cyclic part, and an exocyclic chain of seven amino acids with a terminal fatty acid group. Originally kahalalide F was reported to have the structure (I).  
                 
 
      In WO 04035613 there is described the 4(S)-methylhexyl compound with the following formula (II). WO 04035613 is incorporated here in full by specific reference.  
                 
 
      The activity of kahalalide F against in vitro cell cultures of human lung carcinoma A-549 and human colon carcinoma HT-29 were reported in EP 610 078. Kahalalide F has also demonstrated to have antiviral and antifungal properties, as well as to be useful in the treatment of psoriasis.  
      WO 02 36145 describes pharmaceutical compositions containing kahalalide F and new uses of this compound in cancer therapy and is incorporated herein by reference in its entirety.  
      WO 03 33012 describes the clinical use in oncology of kahalalide compounds and is incorporated herein by reference in its entirety.  
      The synthesis and cytotoxic activities of natural and synthetic kahalalide compounds is described in WO 01 58934, which is incorporated herein by reference in its entirety. WO 01 58934 describes the synthesis of kahalalide F and also of compounds with a similar structure in which the terminal fatty acid chain is replaced by other fatty acids.  
      There is still a need to provide further antitumoral compounds, in particular further kahalalide compounds with improved properties.

     DETAILED DESCRIPTION OF THE INVENTION  
      We have identified analogues of kahalalide F that show significant improvement in activity with respect to kahalalide F.  
      The present invention is directed to compounds of formula 1 
                 
 
 wherein one or more exocyclic or cyclic amino acids have been substituted by other natural or non natural amino acids, have been masked with organic groups or have been removed. The present invention is also directed to compounds of formula 1 wherein the aliphatic methylhexanoic acyl group has been substituted by other acyl groups or has been removed. 
 
 Exocyclic Amino Acids 
 
      Preferred compounds of the invention include those of formula 1 wherein one or more amino acids of the exocyclic chain have been substituted by other natural or non natural amino acids, have been masked with organic groups or have been removed.  
      In particular, preferred compounds include those with 1, 2 or 3 replacement amino acids in the exocyclic chain; and those with 1, 2, 3, 4, 5 or 6 removed amino acids in the exocyclic chain.  
      Especially preferred are those compounds of formula 1 wherein one exocyclic amino acid has been substituted by another natural or non natural amino acid, and/or has been masked with one or more substituent organic groups. This preference is specially applicable to the L-Orn amino acid in position 8.  
      Thus, in one aspect of the present invention, there are provided compounds of formula 1 wherein there is not L-Orn at position 8.  
      The L-Orn can be replaced by D-Orn, or by another natural or non-natural amino acid. For example, the L-Orn can be replaced by a natural amino acid, such as lysine; or a masked natural amino acid, such as arginine or lysine with one or more alkyl, phenyl or oligomethylene substituents, for example N(Me) 2 ,N′(Me) 2 -Arg, N(Me,Ph),N′(Me) 2 -Arg, N(CH 2 ) 4 ,N′(Me) 2 -Arg, N(CH 2 ) 4 ,N′(CH 2 ) 4 -Arg, N ε (Me) 3 -Lys.  
      The L-Orn can be masked. For example, the amino group of the L-Orn may have substituents, notably alkyl substituents that may be further substituted, notably with heterocyclic groups, for example N δ (CHN(CH 2 ) 4 ,N′(CH 2 ) 4 )-Orn; or more complex substituents as in biotinylornithine or Orn(N δ Tfa).  
      Cyclic Amino Acids  
      Other preferred compounds of the invention include those of formula 1 wherein one or more amino acids of the cyclic chain have been substituted by other natural or non natural amino acids, have been masked with organic groups or have been removed.  
      In particular, preferred compounds include those with 1, 2 or 3 replacement amino acids in the cyclic chain.  
      Especially preferred are those compounds of formula 1 wherein one or more amino acids have been substituted by other natural or non natural amino acids, and/or have been masked with organic groups. This preference is specially applicable to the L-Phe amino acid in position 3.  
      Thus, in one aspect of the present invention, there are provided compounds of formula 1 wherein the L-Phe at position 3 has been replaced or masked.  
      The L-Phe can be replaced by D-Phe, or by another natural or non-natural amino acid. For example, the L-Phe can be replaced by a natural amino acid, such as tyrosine; an alkyl-substituted amino acid, such as N-methyltyrosine; an aryl-substituted amino acid, such as 2-amino-3-biphenyl-4-yl-propionic acid, 2-amino-3-naphthalen-2-yl-propionic acid or aminophenylacetic acid; an heterocyclyl-substituted amino acid, such as 2-amino-3-thiophen-2-ylpropionic acid; or a cyclic amino acid where the amino group is part of a heterocycle, such as 1,2,3,4-tetraisoquinoline-3-carboxilic acid or octahydroisoindole-1-carboxylic acid.  
      The L-Phe can be masked. For example, the phenyl ring may be partially or fully saturated, and may be substituted with one or more substituents. Substituents for the phenyl ring may be as indicated, preferably halo or nitro. The amino group may have 1 or 2 substituents, notably alkyl such as methyl, especially 1 methyl substituent.  
      Terminal Acyl Group  
      Besides the modification of the amino acids of the exocyclic chain and/or of the cyclic part, there can also be compounds with a modification in the terminal acyl group of the exocyclic chain.  
      For example, the acyl group can comprise one or more substituents, especially aromatic, heterocyclic or carbocyclic groups which in turn may have one or more substitutents, for example can be a benzoyl group which may have one or more substituents, a phenylalkanoyl which may have one or more substituents or a cinnamoyl which may have one or more substituents. Additionally, the terminal acyl group can be another fatty acid typically a saturated or unsaturated fatty acid with 3 to 26 carbon atoms, more especially 12 to 20 carbon atoms.  
      Typical groups for adoption in place of the terminal acyl group in formula 1 include: 
          Straight chain alkanoyl with up to 26 carbon atoms and with one or more substituents, especially substituents chosen from optionally substituted cycloalkyl such as 4-methylcyclohexyl; alkyl, especially short chain alkyl such as methyl; optionally substituted aryl especially phenyl such as difluorophenyl; halo such as fluoro up to perfluoro; oxo; amino; or imino.     Optionally substituted benzoyl such as benzoyl itself, p-methylbenzoyl acid, p-trifluoromethylbenzoyl acid, piperonyloyl.     Arylalkenoyl group with preferably two carbon atoms in the alkenoyl especially a cinnamoyl group such as p-trifluoromethylcinnamoyl.        

      Moreover, the acyl group can be replaced by another acyl group, preferably of formula R′CO—. R′ is as defined and is suitably alkyl, alkenyl, aryl, heterocyclyl, or carbocyclyl, and may itself be substituted.  
      Finally, there can be compounds with a unique modification located in the fatty acid of the exocyclic chain, the provision of a 5-methyhexyl terminal group.  
      Combined Changes  
      The possible changes in the exocyclic amino acids, cyclic amino acids and terminal acyl group can be taken in combination.  
      Thus, other preferred compounds of the invention are those of formula 1 wherein one or more amino acids of the exocyclic chain and/or one or more amino acids of the cyclic part have been modified, as mentioned above and/or the terminal acyl group has been modified.  
      The compounds where the L-Orn at position 8 has been replaced or masked may adopt other preferred modifications, including a 4(S)-methylhexyl or other group in the terminal group of the sidechain.  
      The compounds where the L-Phe at position 3 has been replaced or masked may adopt other preferred modifications, including a 4(S)-methylhexyl or other group in the terminal group of the sidechain.  
      Examples of substituent groups include C 1 -C 18  alkyl, C 2 -C 18  alkenyl, C 2 -C 18  alkynyl, aryl, heterocyclic groups, OR′, SR′, SOR′, SO 2 R′, NO 2 , NHR′, N(R′) 2 , NHCOR′, N(COR′) 2 , NHSO 2 R′, CN, halogen, C(═O)R′, CO 2 R′, OC(═O)R′ wherein each of the R′ groups is independently selected from the group consisting of H, OH, NO 2 , NH 2 , SH, CN, halogen, C(═O)H, C(═O)alkyl, CO 2 H, substituted or unsubstituted C 1 -C 18  alkyl, substituted or unsubstituted C 2 -C 18  alkenyl, substituted or unsubstituted C 2 -C 18  alkynyl and substituted or unsubstituted aryl. Suitable halogen substituents in the compounds of the present invention include F, Cl, Br and I.  
      Alkyl groups have a saturated linear or branched hydrocarbon group including, for example, methyl, ethyl, isopropyl, isobutyl, t-butyl, heptyl, dodecyl, octadecyl, amyl, 2-ethylhexyl, 2-methylbutyl, 5-methylhexyl, 9-methyl-3-decyl, and the like, particularly alkyl groups which have a single branched methyl group. Suitably the alkyl group is long and has 1 to 20 carbon atoms, more typically 1 to 15 or 1 to 10 carbon atoms, or can be short and has 1 to 6 or 1 to 3 carbon atoms. Long carbon chains are candidates for use in the terminal fatty acid group.  
      Preferred alkenyl and alkynyl groups in the compounds of the present invention have one or more unsaturated linkages and from 2 to 12 carbon atoms, more preferably 2 to 8 carbon atoms, still more preferably 2 to 6 carbon atoms, even more preferably 2, 3 or 4 carbon atoms. The terms alkenyl and alkynyl as used herein refer to both cyclic and noncyclic groups, although straight or branched noncyclic groups are generally more preferred. In a general sense, we include alkylidene within alkenyl, they both being substituents with a double bond.  
      Suitable aryl groups in the compounds of the present invention include single and multiple ring compounds, including multiple ring compounds that contain separate and/or fused aryl groups. Typical aryl groups contain from 1 to 3 separated or fused rings and from 6 to about 18 carbon ring atoms. Specifically preferred aryl groups include substituted or unsubstituted phenyl, naphthyl, biphenyl, phenanthryl and anthracyl.  
      Suitable acyl groups include alkanoyl groups which have from 2 to about 12 carbon atoms, more preferably from 2 to about 8 carbon atoms, still more preferably from 2 to about 6 carbon atoms, even more preferably 2 carbon atoms. Other acyl groups include alkenylacyl, alkynylacyl, arylacyl, heterocyclylacyl.  
      Suitable heterocyclic groups include heteroaromatic and heteroalicyclic groups. Suitable heteroaromatic groups in the compounds of the present invention contain one, two or three heteroatoms selected from N, O or S atoms and include, e.g., coumarinyl including 8-coumarinyl, quinolinyl including 8-quinolinyl, pyridyl, pyrazinyl, pyrimidyl, furyl, pyrrolyl, thienyl, thiazolyl, oxazolyl, imidazolyl, indolyl, benzofuranyl and benzothiazol. Suitable heteroalicyclic groups in the compounds of the present invention contain one, two or three heteroatoms selected from N, O or S atoms and include, e.g., tetrahydrofuranyl, tetrahydropyranyl, piperidinyl, morpholino and pyrrolindinyl groups.  
      The groups above mentioned may be substituted at one or more available positions by one or more substituents.  
      The natural amino acids include alanine, glycine, valine, leucine, isoleucine, phenylalanine, tyrosine, tryptophan, methionine, cysteine, aspartate, asparagine, glutamatic acid, glutamine, lysine, arginine, proline, serine, threonine, histidine and hydroxyproline

      As used herein, the compounds of this invention, including the compounds of formula 1, are defined to include pharmaceutically acceptable derivatives or prodrugs thereof A “pharmaceutically acceptable derivative or prodrug” means any pharmaceutically acceptable salt, ester, salt of an ester or other derivative of a compound of this invention that, upon administration to a recipient, is capable of providing (directly or indirectly) a compound of this invention or a metabolite or residue thereof. Particularly favoured derivatives and prodrugs are those that increase the bioavailability of the compounds of this invention when such compounds are administered to a patient (e.g., by allowing an orally administered compound to be more readily absorbed into the blood), enhance delivery of the parent compound to a given biological compartment, increase solubility to allow administration by injection, alter metabolism or alter rate of excretion.  
      Salts of the compounds of the present invention may comprise acid addition salts derived from a nitrogen in the compound of formula 1 or 2. The therapeutic activity resides in the moiety derived from the compound of the invention as defined herein and the identity of the other component is of less importance although for therapeutic and prophylactic purposes it is, preferably, pharmaceutically acceptable to the patient. Examples of pharmaceutically acceptable acid addition salts include those derived from mineral acids, such as hydrochloric, hydrobromic, phosphoric, metaphosphoric, nitric and sulphuric acids, and organic acids, such as tartaric, acetic, trifluoroacetic, citric, malic, lactic, fumaric, benzoic, glycolic, gluconic, succinic and methanesulphonic and arylsulphonic, for example p-toluenesulphonic, acids. Preferred salts include the trifluoroacetate salt and the hydrochloride salt.  
      The compounds of the present invention can be prepared according to the synthetic process described in WO 01 58934, or according to the improved process as described herein. Therefore also encompassed by the invention is a process to prepare a compound according to formula 1.  
      The key steps of the optimized process for a more economical and safe synthesis of kahalalide F and its analogues are: (i) partial incorporation of Fmoc-D-Val-OH onto the chlorotritylchloro-polystyrene resin for a initial loading of 0.5 mmol/g; (ii) use as coupling method of DIPCDI-HOBt, instead of HATU-DIPEA, for the sequential incorporation of the protected amino acids and aliphatic carboxylic acids; (iii) cyclization step with DIPCDI/HOBt/DIPEA in CH 2 Cl 2 ; these conditions avoids two side reaction: epimerisation of the Val residue, which is involved in the activation, and trifluoroacetylation of the Phe or its replacement; (iv) use of sodium diethyl-dithiocarbamate after removing Alloc to avoid presence of Pd (0) in the final product.  
      The synthesis is preferably a solid phase synthetic process.  
      The preferred embodiment of the synthetic process of the present invention is best represented in the Scheme 1, which is directed to the formation of the target compounds.  
                 
 
      As shown above in Scheme 1, the preferred process for the synthetic formation of analogues of kahalalide F is based in a solid-phase approach, see for example Lloyd-Williams, P., et al.  Chemical Approaches to the Synthesis of Peptides and Proteins . CRC Press, Boca Raton (Fla.), 1997 and followed with modifications of the method already described for the preparation kahalalide F and some of its analogues (WO 01 58934).  
      The process of Scheme 1 comprises the sequential steps of:  
      (a) incorporating an Fmoc-DVal-OH onto a chlorotrityl chloro resin, forming an ester bond;  
      (b) elongating the peptidic chain with three amino acids [Dalle, DaThr (free OH), Dalle) using a Fmoc/tBu strategy;  
      (c) incorporating [Val(1)] using an Alloc/tBu strategy;  
      (d) elongating the peptidic chain with the remaining amino acids and aliphatic carboxylic acids using a Fmoc/tBu strategy;  
      (e1) incorporating the dipeptide Alloc-Phe-ZDhb-OH, which has been combined and dehydrated in solution;  
      (e2a) elongating the peptidic chain with two amino acids, preferably Thr and Phe. The OH of Thr is unprotected and the amino group of Phe, or its replacement, is protected with Fmoc or preferably with Alloc; in some cases if it is protected with Fmoc, this is removed and Alloc is introduced in solid-phase;  
      (e2b) dehydrating in solid-phase to give the didehydropeptide;  
      (f) removing the Alloc/Fmoc group of Phe, or of its replacement, while the peptide is still anchored to the solid support;  
      (g) cleaving the side-chain protected peptide from the solid support;  
      (h) cyclizing the peptide in solution;  
      (i) removing TFA labile side chain protecting groups.  
      (j) Further modifications of functional(s) group(s) in solution phase.  
      Therefore the process can be conducted as follows:  
      Fmoc-DVal-OH is incorporated preferably to a chlorotrityl-polystyrene resin, see Barlos, K.; Gatos, D.; Schäfer, W. Angew. Chem. Int. Ed. Engl. 1991, 30, 590-593, in the presence of DIPEA keeping the level of substitution of aprox. 0.5 mmol/g. The use of higher loadings brings the presence of terminated peptides in the final product, see Chiva, C.; Vilaseca, M.; Giralt, E.; Albericio, F. J. Pept. Sci. 1999, 5, 131-140.  
      All solvent ratios are volume/volume unless stated otherwise.  
      Removal of the Fmoc group can be carried out with piperidine-DMF (2:8, v/v) (1×2 min, 2×10 min). Couplings of Fmoc-aa-OH (4-5 equiv) and the acids at the 14-position can be carried out with DIPCDI-HOBt (equimolar amounts of each one respect to the carboxylic component) or PyBOP-DIPEA (equimolar amount of PyBOP and double amount of DIPEA) in DMF or DMF-Toluene (1:1) for 90 min. After the coupling ninhydrin or chloranil tests are carried out and if it is positive the coupling is repeated in the same conditions, otherwise the process is continued. Washings between deprotection, coupling, and, again, deprotection steps can be carried out with DMF (5×0.5 min) and CH 2 Cl 2  (5×0.5 min) using for example each time 10 mL solvent/g resin.  
      Incorporation of Alloc-Val-OH (5 equiv) can be carried out with equimolar amount of DIPCDI and 10% of DMAP. This coupling is repeated at least twice.  
      Removal of Alloc group can be carried out with Pd(PPh 3 ) 4  (0.1 equiv) in the presence of PhSiH 3  (10 equiv), see Gómez-Martínez, P.; Thieriet, N.; Albericio, F.; Guibé, F. J. Chem. Soc. Perkin I 1999, 2871-2874, and washing the resin with sodium diethyldithiocarbamate in DMF 0.02 M (3×15 min).  
      The dipeptide Alloc-Phe-ZDhb-OH (4 equiv), which was prepared in solution from Alloc-Phe-OH and H-Thr-OtBu with EDC.HCl, and posterior dehydration and treatment with TFA, can be coupled with DIPCDI-HOAt (4 equiv of each) for 5 h to overnight. The use of other coupling reagents based in HOBt, such as HBTU or DIPCDI-HOBt, has led to incomplete incorporations of the dipeptide.  
      Dehydration can be carried out in solid-phase with EDC.HCl (water soluble carbodiimide, 20 equiv) in the presence of CuCl (12 equiv) in CH 2 Cl 2 -DMF (9:1) for 7 days. EDC.HCl/CuCl has been used by dehydration in solution of a residue of Thr in a fragment of Nisin (Fukase, K.; Kitazawa, M.; Sano, A.; Shimbo, K.; Horimoto, S.; Fujita, H.; Kubo, A.; Wakamiya, T.; Shibe, A. Bull. Chem. Soc. Jpn. 1992, 65, 2227-2240) and in solid-phase for the preparation of didehydropeptides from Thr, Ser, and phenylserine (Royo, M.; Jiménez, J. C.; López-Macià, A.; Giralt, E.; Albericio, F. Eur. J. Org. Chem. 2001, 45-48).  
      Cleavage of the protected peptide from the resin can be accomplished by TFA-CH 2 Cl 2  (1:99) (5×30 sec).  
      Cyclization step can be carried out with DIPCDI/HOBt/DIPEA in CH 2 Cl 2 . These conditions avoid two side reactions: epimerisation of the Val residue, which is involved in the activation, and trifluoroacetylation of the Phe or its replacement.  
      Final deprotection can be carried out with TFA-H 2 O (95:5) for 1 hour.  
      It will be appreciated that the particular choice of protecting groups is not critical, and other choices are widely available. For example, Bzl type groups can replace tBu/Boc; Boc instead of Fmoc; Fmoc instead of Alloc; Wang resin instead of chlorotrityl.  
      Further detail on the synthesis is given in the examples.  
      The process of this invention can be carried out from starting materials in an enantio-, stereocontrolled and fast manner, taking advantages of the solid-phase synthetic methodology, where the molecule in construction is bounded to an insoluble support during all synthetic operations.  
      Pharmaceutical formulations of the compounds of the invention may be adapted for administration by any appropriate route, for example by the oral (including buccal or sublingual), rectal, nasal, topical (including buccal, sublingual or transdermal), vaginal or parenteral (including subcutaneous, intramuscular, intravenous or intradermal) route. Such formulations may be prepared by any method known in the art of pharmacy, for example by bringing into association the active ingredient with the carrier (s) or excipient (s).  
      Preferably pharmaceutical compositions of the compounds of the invention include liquid (solutions, suspensions or emulsions) with suitable composition for intravenous administration, and they may contain the pure compound or in combination with any carrier or other pharmacologically active compounds. Further guidance concerning the pharmaceutical compositions can be found in WO 02 36145 which is incorporated herein by reference in its entirety.  
      Thus, a combination of a non-ionic surfactant and an organic acid is suited for use with a bulling agent to give a lyophilised form of a compound of the invention suited for reconstitution. Reconstitution is preferably effected with a mix of emulsifying solubiliser, alkanol and water.  
      The lyophilised composition preferably comprises mainly the bulking agent, such as at least 90% or at least 95% bulking agent. Examples of bulking agents are well known and include sucrose and mannitol. Other bulking agents can be employed.  
      The non-ionic surfactant in the lyophilised composition is preferably a sorbitan ester, more preferably a polyethylene sorbitan ester, such as a polyoxyethylene sorbitan alkanoate, especially a polyoxyethylene sorbitan mono-oleate, for example polysorbate 80. The non-ionic surfactant typically comprises a few % of the composition, such as 0 to 5% of the composition, for instance 2 to 3 or 4% of the composition.  
      The organic acid in the lyophilised composition is typically an aliphatic acid, preferably a hydroxycarboxylic acid and more preferably a hydroxypolycarboxylic acid, notably citric acid. The organic acid typically comprises a few % of the composition, such as 0 to 5% of the composition, for instance 2 to 3 or 4% of the composition.  
      The amount of the compound of the invention in the lyophilised composition is typically less than 1%, or often less than 0.1%, of the mix. A suitable amount is in the range 50 to 200 μg, say about 100 μg, per 100 mg of composition.  
      The emulsifying solubiliser for the reconstituting agent suitably comprises an polyethylene glycol ester, notably an ester of a fatty acid, more preferably a PEG oleate such as PEG-35 oleate. The emulsifying solubiliser is suitably 0 to 10% of the reconstituting agent, typically about 3 to 7%, say about 5%. The alkanol is usually ethanol, and is suitably 0 to 10% of the reconstituting agent, typically about 3 to 7%, say about 5%. The remainder of the reconstituting agent is water, and gives a reconstituted solution suited for intravenous injection.  
      Further dilution of the reconstituted solution with 0.9% saline may be appropriate for infusion of the kahalalide compound. Suitable infusion equipment preferably includes a glass container, rather than one of polyethylene. Tubing is preferably of silicone.  
      The preferred reconstituting agent then comprises 2 to 7%, say about 5%, emulsifying solubiliser; 2 to 7%, say about 5%, alcohol; and remainder water.  
      The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use.  
      The invention additionally provides kits comprising separate containers containing the lyophilised composition and the reconstituting agent. Methods of reconstitution are also provided.  
      Administration of the compounds or compositions of the present invention is by intravenous infusion. Infusion times of up to 72 hours can be used, more preferably 1 to 24 hours, with either about 1 or about 3 hours most preferred. Short infusion times which allow treatment to be carried out without an overnight stay in hospital are especially desirable. However, infusion may be around 24 hours or even longer if required.  
      The administration is performed in cycles, in the preferred application method, an intravenous infusion of a compound of the invention is given to the patients the first week of each cycle, the patients are allowed to recover for the remainder of the cycle. The preferred duration of each cycle is of either 1, 3 or 4 weeks; multiple cycles can be given as needed. In an alternative dosing protocol, the compound of the invention is administered for say about 1 hour for 5 consecutive days every 3 weeks. Other protocols can be devised as variations.  
      Dose delays and/or dose reductions and schedule adjustments are performed as needed depending on individual patient tolerance of treatments, in particular dose reductions are recommended for patients with higher than normal serum levels of liver transaminases or alkaline phosphatase.

     Step 1  
     H-D-Val-O-TrtCl-resin  
      Cl-TrtCl-resin (1 g, 1.64 mmol/g) was placed in a 20 mL polypropylene syringe fitted with a polyethylene filter disk. The resin was then washed with CH 2 Cl 2  (5×0.5 min), and a solution of Fmoc-D-Val-OH (238 mg, 0.7 mmol, 0.7 equiv) and DIPEA (0.41 mL) in CH 2 Cl 2  (2.5 mL) was added, and the mixture was stirred for 15 min, when extra DIPEA (0.81 mL, total 7 equiv, 7 mmol) and the mixture stirred for 45 min. The reaction was terminated by addition of MeOH (800 μL), after a stirring of 10 min. The Fmoc-D-Val-O-TrtCl-resin was subjected to the following washings/treatments with CH 2 Cl 2  (3×0.5 min), DMF (3×0.5 min), piperidine as indicated in General Procedures, and DMF (5×0.5 min). The loading calculated by Fmoc determination was 0.50 mmol/g.  
     Step 2  
     Fmoc-D-allo-Ile-D-allo-Thr(Val-Alloc)-D-allo-Ile-D-Val-O-TrtCl-resin  
      Fmoc-D-allo-Ile-OH (707 mg, 2 mmol, 4 equiv), Fmoc-D-allo-Thr-OH (free hydroxy group) (683 mg, 2 mmol, 4 equiv), and Fmoc-D-allo-Ile-OH (707 mg, 2 mmol, 4 equiv) were added sequentially to the above obtained H-D-Val-O-TrtCl-resin using DIPCDI (310 μL, 2 mmol, 4 equiv) and HOBt (307 mg, 2 mmol, 4 equiv) in DMF (2.5 mL). In all cases, after 90 min of coupling, the ninhydrin test was negative. Removal of Fmoc group and washings were carried out as described in General Procedures. Alloc-Val-OH (502 mg, 2.5 mmol, 5 equiv) was coupled with DIPCDI (387 mg, 2.5 mmol, 5 equiv) in the presence of DMAP (30.6 mg, 0.25 mmol, 0.5 equiv) and DIPEA (88 μL, 0.5 mmol, 1 equiv) for 45 min. This coupling was repeated in the same conditions twice. An aliqout of the peptidyl-resin was treated with TFA and the HPLC (t R  7.8 min, conditions S, column D) of the crude obtained after evaporation showed a purity of &gt;98%. ESMS, calcd for C 45 H 63 N 5 O 11 , 849.45. Found: m/z 850.1 [M+H] + .  
     Step 3  
     Fmoc-D-Val-D-Pro-Orn(Boc)-D-allo-Ile-D-allo-Thr(Val-Alloc)-D-allo-Ile-D-Val-O-TrtCl-resin  
      The Fmoc group was removed and Fmoc-Orn(Boc)-OH (912 mg, 2 mmol, 4 equiv), Fmoc-D-Pro-OH (843 mg, 2.5 mmol, 5 equiv), and Fmoc-D-Val-OH (255 mg, 2.5 mmol, 5 equiv) were sequentially added to the above peptidyl-resin (Step 2) using DIPCDI (310 μL, for 2.0 mmol and 4 equiv; and 388 μL, for 2.5 mmol, 5 equiv) and HOBt (307 mg, for 2.0 mmol and 4 equiv; and 395 mg, 2.5 mmol. 5 equiv) for 90 min. Ninhydrin test after incorporation of Orn and D-Pro was negative.

     (4S)-MeHex-D-Val-Thr(tBu)-Val-D-Val-D-Pro-Orn(Boc)-D-allo-Ile-D-allo-Thr(Val-Z-Dhb-Phe-H)-D-allo-Ile-D-Val-OH  
      After washings with DMF and CH 2 Cl 2 , the Alloc group was removed with Pd(PPh 3 ) 4  (58 mg, 0.05 mmol, 0.1 equiv) in the presence of PhSiH 3  (617 μL, 5 mmol, 10 equiv) under atmosphere of Ar. The protected peptide was cleaved from the resin by TFA-CH 2 Cl 2  (1:99) (5×30 sec). Filtrate was collected on H 2 O (4 mL) and the H 2 O was partially removed in a rotavapor. ACN was then added to dissolve solid that appeared during the H 2 O removal, and the solution was lyophilized, to give 639 mg (387 μmol, 77% yield) of the title compound with a purity of &gt;95% as checked by HPLC (Condition R, column C, t R  10.5 min).  
     Step 7  
     (4S)-MeHex-D-Val-Thr-Val-D-Val-D-Pro-Orn-D-allo-Ile-cyclo(D-allo-Thr-D-allo-Ile-D-Val-Phe-ZDhb-Val)  
      The protected peptide (Step 6) (639 mg, 387 μmol) was dissolved in CH 2 Cl 2  (390 mL, 1 mM), and HOBt (237 mg, 1.55 mmol) dissolved in the minimum volume of DMF to dissolve HOBt, DIPEA (203 μL, 1.16 mmol, 3 equiv), and DIPCDI (240 μL, 1.55 mmol, 4 equiv) were added. The mixture was allowed to stir for 1 h, then the course of the cyclization step was checked by HPLC. The solvent was removed by evaporation under reduced pressure. The protected cyclic peptide was dissolved in TFA-H 2 O (19:1, 85 mL) and the mixture was allowed to stir for 1 h. The solvent was removed by evaporation under reduced pressure, and dioxane is added (30 mL) and the solvent is removed by evaporation under reduced pressure (the process was repeated three times), then H 2 O (40 mL) was added and lyophilized. The crude product was purified by HPLC (Kromasil C 8  5 μm, 205×50 mm), isocratic 44% acetonitrile (+0.05% TFA) in water (+0.05% TFA), 55 mL/h, detection at 220 nm, to give the title product (192 mg, 0.13 mmol, 26% yield, 92.3%).

      A colorimetric type of assay, using sulforhodamine B (SRB) reaction has been adapted for a quantitative measurement of cell growth and viability [following the technique described by Philip Skehan, et al. (1990), New colorimetric cytotoxicity assay for anticancer drug screening,  J. Natl. Cancer Inst.,  82:1107-1112].  
      This form of the assay employs 96 well cell culture microplates of 9 mm diameter (Faircloth, 1988; Mosmann, 1983). Most of the cell lines are obtained from American Type Culture Collection (ATCC) derived from different human cancer types.  
      Cells are maintained in RPMI 1640 10% FBS, supplemented with 0.1 g/l penicillin and 0.1 g/l streptomycin sulfate and then incubated at 37° C., 5% CO 2  and 98% humidity. For the experiments, cells were harvested from subconfluent cultures using trypsin and resuspended in fresh medium before plating.  
      Cells are seeded in 96 well microtiter plates, at 5×10 3  cells per well in aliquots of 195 μL medium, and they are allowed to attach to the plate surface by growing in drug free medium for 18 hours. Afterward, samples are added in aliquots of 5 μL in a ranging from 10 to 10 −8  μg/mL, dissolved in DMSO:EtOH:PBS (0.5:0.5:99). After 48 hours exposure, the antitumor effect are measured by the SRB methodology: cells are fixed by adding 50 μL of cold 50% (wt/vol) trichloroacetic acid (TCA) and incubating for 60 minutes at 4° C. Plates are washed with deionized water and dried. One hundred μL of SRB solution (0.4% wt/vol in 1% acetic acid) is added to each microtiter well and incubated for 10 minutes at room temperature. Unbound SRB is removed by washing with 1% acetic acid. Plates are air dried and bound stain is solubilized with Tris buffer. Optical densities are read on a automated spectrophotometric plate reader at a single wavelength of 490 nm.  
      The values for mean+/− SD of data from triplicate wells are calculated. Some parameters for cellular responses can be calculated: GI=growth inhibition, TGI=total growth inhibition (cytostatic effect) and LC=cell killing (cytotoxic effect).
