Description: SUBSTITUTED ISOQUINOLINES AS ULTRA SHORT ACTING NEUROMUSCULAR BLOCKERS The present invention relates to novel compounds, methods for the preparation of such compounds, pharmaceutical compositions containing them and their use as neuromuscular blocking agents of ultra-short duration. In anesthesia, neuromuscular blocking agents are used to provide skeletal muscle relaxation during surgery and during intubation of the trachea. Neuromuscular blockers are generally classified by both the mechanism of action (depolarizing or non- depolarizing) and the duration of action (ultrashort, short, intermediate, and long). See, Bedford, R., "From the FDA", Anesthesiology, 82(1), 33a, 1995. Non-depolarizing neuromuscular blocking agents include long-duration agents such as d-tubocurarine, pancuronium, gallamine, diallyltoxiferine and toxiferine, intermediate-duration agents such as atracurium and vecuronium, and short-duration agents such as mivacurium. See e.g., U.S. 4,179,507, U.S. 4,701,460, U.S. 4,761,418 and U.S. 5,454,510. Conventional non-depolarizing agents typically exhibit a 20 to 180 minute duration of action when used as skeletal muscle relaxants. Presently there are no ultrashort duration, non-depolarizing neuromuscular blocking agents in clinical use. Depolarizing agents include succinylcholine and decamethonium. Due to their depolarizing mechanism of action, these agents can have severe side effects such as cardiac arrest and death, hyperkalemia, malignant hyperthermia, severe muscle pain, cardiac arrhythmias, increased intraocular pressure and increased intragastric tension. Conventional depolarizing agents exhibit shorter durations of action, e.g., 10 to 15 minutes in humans. Succinylcholine has a rapid onset and ultrashort duration of action and is the only ultra-short acting neuromuscular blocker in clinical use. Despite its undesirable side effect profile, no other ultrashort acting agent is available and thus it is currently the preferred agent for emergency use. The ultra-short duration of action is extremely important in emergency situations. Use of longer duration agents could lead to serious brain damage and death. Non-depolarizing agents are generally believed to be safer and more clinically desirable than depolarizing agents, and clinicians have long recognized the need for a non- depolarizing neuromuscular blocker that has an ultra-short duration of action. See, Miller, R.D. Anesthesia and Analgesia 61(9), 721, 1982; and Belmont, M.R., Current Opinion in Anaesthesiology, 8, 362, 1995. However, non-depolarizing agents can exhibit side effects not specifically related to their mechanism or duration of action. For example, the long-duration agents pancuronium and gallamine have effects on the autonomic nervous system and may cause an increase in heart rate (tachycardia). Intermediate- and short-duration agents such as atracurium besylate and mivacurium chloride may also exhibit the side effect of histamine release. Histamine release has undesirable effects on blood pressure and heart rate, and some physicians believe that release of large amounts of histamine can cause life-threatening anaphylaxis in some patients. It has now been discovered that compounds of Formula (I) include potent non- depolarizing neuromuscular blocking agents of ultra-short duration, e.g., about 5 to 15 minutes, that will provide both increased safety over known depolarizing ultrashort acting agents, e.g. succinylcholine, and a reduced capacity to release histamine over other non-depolarizing agents such as atracurium and mivacurium. In addition, they have a rapid onset of action and are reversed by treatment with known reversal agents such as neostigmine, both very important features in emergency situations and procedures. These agents maintain their ultrashort duration of action and rapid spontaneous recovery when administered by either bolus or continuous infusion and are without the cumulative effects observed with other neuromuscular blockers (pancuronium, vecuronium). Thus, compounds of the present invention should provide a significant advantage in the emergency, routine surgical, and post-operative settings. Accordingly, the present invention provides compounds of Formula (I): 1 1 wherein q and t are independently from 0 to 4; X and X are independently halogen; h a and h b are independently from 0 to 2; Z and Z are independently hydrogen, C^ 1 2 alkyl, C 2 . 6 alkenyl or C 2-6 alkynyl with the proviso that Z and Z are not both hydrogen; γ i ^ γ 2 γ 3 an( j γ are i n( j e en d en tiy hydrogen, halogen or C 1-3 alkoxy; m and p are independently 1 to 6; n and r are independently 0 to 4 ; with the proviso that if h a and h b are both 0, then r is 0 and n is 0 to 2; R 1 to R are independently hydrogen, halogen, C j _ 3 alkoxy, or R and R together with the carbon atoms to which they are bonded, R and R 6 together with the carbon atoms to which they are bonded, R and R 10 together with 12 1 the carbon atoms to which they are bonded and R and R together with the carbon atoms to which they are bonded, may independently form a methylenedioxy or 1 9 ethylenedioxy moiety contained in a five or six-membered ring; W and W are carbon; and A is a pharmaceutically acceptable anion. The compounds of Formula (I) contain two substituted isoquinolinium moieties connected by an aliphatic linker. The two substituted isoquinolinium moieties can be conveniently distinguished by referring to them as the "left head" and the "right head", where the left head contains W and the right head contains W . The aliphatic linker is the portion of the compound of Formula (I) denoted by the following Formula (i). The bond between the carbons attached to (CH 2 ) q and (CH 2 ) t , indicated as ( ), may be a single or double bond. The compounds of Formula (I) may exhibit structural asymmetry in several ways. For example, a preferred sub-class of the compounds of Formula (I) is wherein n and r are different. A more preferred sub-class includes those wherein n is 1 and r is 0, i.e., one head contains a benzyl substitution whereas the other head contains a phenyl substitution. Suitable aliphatic linkers include those where q and t are the same and are 0, 2 or 3. Preferred linkers include succinate, butenedioate, particularly fumarate, octanedioate and decanedioate. Particularly preferred aliphatic linkers comprise succinate or fumarate moieties, i.e., where q and t are each 0. A preferred sub-class of the compounds of Formula (I) includes those where the aliphatic linker is halogenated, i.e., where h a and h are independently from 1 to 2. Preferred halogens are chlorine, bromine or fluorine, especially chlorine and fluorine. Particularly preferred halogen substitutions are monochloro, monofluoro and difluoro. The most preferred sub-class includes compounds where the aliphatic linker contains a succinate moiety and where the halogen substitution is difluoro or where the aliphatic linker contains a fumarate moiety and the halogen substitution is monochloro or monofluoro. The position of the halogen substitution may also confer asymmetry to the compounds of Formula (I). For example, it is preferred that the halogen substitution be situated proximal to the left head when n is 1 and r is 0, i.e., the left head contains a benzyl substitution and the right head contains a phenyl substitution. Suitable compounds of Formula (I) include those wherein Y 1 , Y 2 , Y 3 and Y 4 are each independently hydrogen or methoxy. Preferably Y and Y are hydrogen and Y and Y 4 are methoxy. Further suitable compounds of Formula (I) include those wherein R r R 14 are each independently hydrogen or C 1-3 alkoxy. Preferably R , R , R , R , R and R 14 are hydrogen and R 2 , R 3 , R 5 , R 6 , R 9 , R 10 , R 12 and R 13 are C 1-3 alkoxy. A more preferred sub-class of the compounds of Formula (I) include those where R 1 , R 4 , R 7 , R 8 , R 11 and R 14 are hydrogen and R 2 , R 3 , R 5 , R 6 , R 9 , R 10 , R 12 and R 13 are C 1-3 alkoxy and where Y 1 and Y are hydrogen and where Y and Ϊ are methoxy. It is preferred that when R and together with the carbon atoms to which they are bonded, R and R together with the 12 13 carbon atoms to which they are bonded, or R and R together with the carbon atoms to which they are bonded independently form a methylenedioxy or ethylenedioxy moiety contained in a five or six-membered ring, that the ring is a five-membered ring containing a methylenedioxy moiety. Particularly suitable compounds of Formula (I) include those wherein q and t are 0; X 1 is halogen; h a is from 1 to 2 and h is zero; Z and Z 2 are methyl; Y 1 is hydrogen or methoxy, Y is methoxy Y is hydrogen and Ϊ is methoxy; m and p are 3; n is 1 and r is zero; R 1 , R 4 , R 7 , R 8 , R 11 and R 14 are hydrogen and R 2 , R 3 , R 5 , R 6 , R 9 , R 10 , R 12 and R 13 1 2 are methoxy; W and W are carbon; and A is a pharmaceutically acceptable anion. The compounds of Formula (I) contain four chiral centres. The carbon atoms (denoted as W and W 2 ) and each quaternary nitrogen atom in the isoquinolinium moieties are chiral. Each of the four chiral centres may independently exist in either the R or S configuration. Accordingly, it would be apparent to those skilled in the art that each compound within Formula (I) may exist in sixteen distinct optical isomeric forms. The scope of the present invention extends to cover each and every isomer of the compounds of Formula (I) either individually or in admixture with other isomers, and all mixtures of such isomers. It is preferred that when n is 1 and r is 0, that W 1 is in the R configuration, W is in the S configuration, the N attached to Z is in the S configuration and the N attached to Z is in the R configuration. The compounds of Formula (I) may also contain an alkenic double bond in the aliphatic linker and may, therefore, exist in either the E or Z configuration. A preferred sub-class of the compounds of Formula (I) include those having the Z configuration. For example, a preferred sub-class of the compounds of Formula (I) includes those where the aliphatic linker comprises a butenedioate moiety, which is preferably a fumarate moiety.

Since the pharmacological activity of the compounds of the invention resides in the cation, the nature of the anion A " is relatively unimportant. However, for therapeutic purposes it is, preferably, pharmaceutically acceptable to the recipient of the compounds. Examples of pharmaceutically acceptable anions include iodide, mesylate, tosylate, bromide, chloride, hydrogen sulphate, sulphate/2, phosphate/3, hydrogen phosphate/2, acetate, besylate, succinate/2, maleate, naphthalenesulphonate and propionate. Both pharmacologically acceptable salts and salts which are not thus acceptable may be useful for isolating and/or purifying the compounds of the invention. The unacceptable salts may also be useful in that they may be converted into acceptable salts by techniques well known in the art. The compounds of Formula (I) are used as neuromuscular blocking agents during surgery, for intubation of the trachea or during electroshock therapy. They may be administered parenterally, e.g., by intramuscular or intravenous injection of a solution. Accordingly, the present invention also provides a method for producing muscle relaxation in a mammal, which comprises administering to the mammal an effective neuromuscular blocking amount of a compound of Formula (I). The dosage for each subject may vary, however, a suitable intravenous amount or dosage of the compounds of Formula (I) to obtain paralysis in mammals would be 0.01 to 5.0 mg/kg of body weight, and most preferably, 0.02 to 0.5 mg/kg of body weight, the above being based on the weight of the di-cation which is the active ingredient. The dosage for intramuscular administration is two to eight times the intravenous dose. In a further aspect, the present invention provides compounds of Formula (I) for use in therapy, for example to induce neuromuscular blockade in surgery or for intubation of the trachea. The present invention also provides the use of a compound of Formula (I) in the manufacture of a medicament for inducing neuromuscular blockade in a mammal, including in a human. While it is possible for the compounds of Formula (I) to be administered as the bulk active chemicals, it is preferred to present them in the form of a pharmaceutical formulation for parenteral administration. Accordingly, the present invention provides a pharmaceutical formulation which comprises a compound of Formula (I), as herein defined and a pharmaceutically acceptable carrier. Where the pharmaceutical formulation is for parenteral administration, the formulation may be an aqueous or non-aqueous solution or mixture of liquids, which may contain bacteriostatic agents, antioxidants, buffers or other pharmaceutically acceptable additives. Alternatively the compounds may be presented as lyophilized solids for reconstitution with water (for injection) or dextrose or saline solutions. Such formulations are normally presented in unit dosage forms such as ampoules or disposable injection devices. They may also be presented in multi-dose forms such as a bottle from which the appropriate dose may be withdrawn. All such formulations should be sterile. A suitable dose to obtain a neuromuscular block for adult humans (150 lbs. or 70 kg) is 0.5 to 150 mg and more preferably 3.5 to 50 mg. The compounds of this invention may optionally be administered before or after (but not simultaneously with) the depolarizing agents as listed above. Thus a suitable pharmaceutical parenteral preparation for administration to humans will preferably contain 0.1 to 20 mg/ml of the compounds of Formula (I) in solution or multiples thereof for multi-dose vials. A simple and preferred formulation is a solution of the compound of Formula (I) in water or dextrose solution. This may be prepared by dissolving the compound in pyrogen-free, sterile water or water containing dextrose, with or without a preservative and sterilizing the solution. Alternatively, it may be prepared by dissolving the sterile compound in pyrogen-free, sterile water or a sterile dextrose solution under aseptic conditions. Particularly preferred formulations have a pH of about 2.0 to 5.0. The compounds of Formula (I) may also be administered as an infusion of a dextrose solution or saline solution, e.g., Ringer's solution in drip form. The compounds may also be administered in other solvents (usually as a mixed solvent with water) such as alcohol, polyethylene glycol and dimethylsulphoxide. They may also be administered intramuscularly (as a drip if required) as a suspension or solution. General Description of Processes Unless otherwise indicated A, h a , h b , m, p, n, r, q, t, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 R 10 R π , R 12 , R 13 , R 14 , W 1 , W 2 , X 1 , X 2 , Y 1 , Y 2 Y 3 , Y 4 , Z 1 and Z 2 described in the formulae which follow are as defined in Formula (I) above and T is hydroxyl or halide. Compounds of Formula (I) may be prepared by reacting two equivalents of a compound of Formula (III) (defined herein): with one equivalent of a compound of Formula (VII) (defined herein): (VII) in an aprotic solvent. The preferred method of coupling compounds of Formula (III) with compounds of Formula (VII) involves mixing the diacid chloride derivative of (VII) (T=C1) with two equivalents of a compound of Formula (III) in a chlorinated organic solvent at ambient or elevated temperatures. Compounds of Formula (I) may be prepared by coupling two different compounds of Formula (III) with one equivalent of a compound of Formula (VII). Reactions of this type are preferably carried out by preparing an equimolar solution of two different compounds of Formula (III) in a chlorinated organic solvent followed by addition of one equivalent of a diacid chloride derivative of (VII) (T=C1). This technique generates a statistical mixture of 3 different compounds of Formula (I) (ignoring stereochemical considerations) and the major component of this mixture is always the compound of Formula (I) containing two different head groups; i.e., a mixed-head compound of Formula (I). One or more of these compounds may be separated from the mixture by chromatographic techniques. This may be followed by the introduction of pharmaceutically acceptable counterions (A-) by conventional ion exchange techniques. Compounds of Formula (III) wherein n is 0 are novel intermediates for the preparation of compounds of Formula (I) and represent a further aspect of the invention. Compounds of Formula (III) may be prepared by two general processes. A first process involves quaternization of compounds of Formula (V) (defined herein): with compounds of Formula (VIII) (defined herein): A(CH 2 ) m OH (VIM) where the substituent A in (VIII) is a suitable leaving group (e.g. A=I, Br, Cl, OSO 2 R, OSO 2 Ar) and corresponds to the anion, A " (defined herein); and optionally converting the anion A ~ in the resulting compound of Formula (III) into another anion (A ~ ) by conventional ion exchange techniques. Reactions of compounds of Formula (V) with compounds of Formula (VIII) are preferably carried out in polar aprotic solvents at elevated temperatures in the presence of sodium carbonate. Compounds of Formula (III) prepared by this process are generated as mixtures of cis/trans stereoisomers and separation of cis/trans isomers of (III) typically requires chromatographic techniques. A second process for the preparation of compounds of Formula (III) is novel and comprises another aspect of the invention. The preparation of compounds of Formula (III) involves alcoholysis of zwitterionic compounds of Formula (IX) (defined herein): Alcoholysis of a compound of Formula (IX) is preferably carried out in methanol solutions of hydrogen chloride at ambient temperature. Compounds of Formula (IX) are prepared by the quatemization of compounds of Formula (V) with cyclic sulfates of Formula (IV) (defined herein): (IV) Reactions of compounds of Formula (V) with compounds of Formula (IV) are preferably carried out in polar aprotic solvents at elevated temperatures. Compounds of Formula (IX) prepared by this process are generated as mixtures of cis/trans isomers; however, cis/trans mixtures of compounds of Formula (IX) may be resolved by selective crystallization of the trans isomer of compounds of Formula (IX) from the mixture. Selective crystallization of trans isomers of compounds of Formula (IX) is preferably accomplished with polar aprotic solvents such as acetonitirile or acetone. This process is the preferred method of preparation of compounds of Formula (III), especially trans isomers of compounds of Formula (III) where the alkanol side chain ((CH2)mOH) and the phenyl (n=0) or benzyl (n=l) substituent are oriented trans to one another in space. Compounds of Formula (IX) wherein n is 0 or 1 are novel intermediates and represent another aspect of the invention. Another aspect of the invention comprises a novel process for the preparation of compounds of Formulae (I) and (II). The preparation of compounds of Formula (I) involves coupling a compound of Formula (II) (defined herein): to a compound of Formula (III). These reactions are preferably carried out by addition of a compound of Formula (III) to the acid chloride derivative of a compound of Formula (II) (T=C1) in a chlorinated organic solvent at ambient or elevated temperatures. The acid chloride derivatives of compounds of Formula (II) (T=C1) may be prepared from the corresponding carboxylic acids of compounds of Formula (II) (T=OH) by methods well known to those skilled in the art. Compounds of Formula (II) (T=OH) are obtained by ring opening of compounds of Formula (VI) (defined herein): (VI) with compounds of Formula (III). These reactions are preferably carried out by mixing compounds of Formulae (III) and (VI) in chlorinated organic solvents at ambient or elevated temperatures. If necessary, these reactions may be facilitated by the addition of a catalyst such as imidazole. These methods may be followed by the introduction of other pharmaceutically acceptable counterions (A-) by conventional ion exchange techniques. Ring opening of monohalogenated cyclic anhydrides of compounds of Formula (VI) (χl=Br, Cl, F; q=0; h b =0) with compounds of Formula (III) can occur selectively to give compounds of Formula (II) (X =Br, Cl, F; T=OH; h b =0; q=0). In these reactions, the hydroxyl group of (III) reacts preferentially at the carbonyl group of compounds of Formula (VI) adjacent to the halogen atom. This process is the preferred method for the preparation of mixed-head compounds of Formula (I) and is even more preferred for the preparation of mixed-head compounds of Formula (I) that contain a halogenated alkanedioate or a halogenated alkenedioate linker. Compounds of Formula (II) wherein n is 0 or 1 are novel intermediates in the preparation of compounds of Formula (I) and represent another aspect of the invention. Another aspect of the invention comprises a novel process for the conversion of one compound of Formula (II) into another compound of Formula (II). Monohalogenated alkenedioates of Formula (lib) (X*=Br, Cl, F; h a =l and q=0): may be prepared by a process which involves elimination of hydrogen halide (HX^) from vicinal dihalo alkanedioates of compounds of Formula (Ila) (X=Br, Cl, F; T=H; h a and h are 1 and q=0): Compounds of Formula (Ila) are prepared by the reaction of compounds of Formula (III) with compounds of Formula (VI) (X=Br, Cl, F; h a and h are independently 1 ; q=0). These reactions are preferably carried out in chlorinated organic solvents at ambient or elevated temperatures. If necessary, these reactions may be facilitated by the addition of a catalyst such as imidazole. These methods may be followed by the introduction of other pharmaceutically acceptable counterions (A ) by conventional ion exchange techniques. The transformation of compounds of Formula (Ila) into compounds of Formula (lib) is typically performed by treatment of (Ila) with an excess of a tertiary amine, such as triethyl amine, in polar aprotic or chlorinated organic solvents at 0°C. In this elimination process, the hydrogen atom (H) vicinal to the ester carbonyl in (Ila) (a to the ester carbonyl) is abstracted selectively. The resulting compounds of Formula (lib) may be converted to monohalogenated alkenedioates of Formula (I) by methods described herein. Another aspect of the invention comprises a novel process for the conversion of one compound of Formula (I) into another compound of Formula (I). Nonhalogenated and monohalogenated alkenedioates of Formula (lb) (X =Br, Cl, F; h a is from 0 to 1 and =0): may be prepared by this process. Nonhalogenated alkenedioates of Formula (lb) (h a =0; t=0) may be prepared by elimination of hydrogen halide (HX 1 ) from monohalo alkenedioates of Formula (la) (X =Br, Cl, F; h a -l; h b =0; t=0): Similarly, monohalogenated alkenedioates of Formula (lb) (X =Br; Cl or F; h a =l; t=0) may be prepared by elimination of hydrogen halide (HX ) from geminal dihalo alkanedioates of Formula (la) (X =Br; Cl or F; h a =2, t=0). This method involves monohaloalkenedioates and geminal dihaloalkanedioates of Formula (la) (X 1= Br, Cl or F; h a =l or 2; t=0) to provide nonhalogenated alkenedioates of Formula (lb) (h a =0; t=0) and monohalogenated alkenedioates of Formula (lb) (X 1= Br, Cl, F; h a =l; t=0), respectively. The hydrogen (H) abstracted in the elimination reactions of this process is typically vicinal to both an ester carbonyl oxygen and the halogen atom(s) in compounds of Formula (la). Eliminations of HX from compounds of Formula (la) are preferably carried out with potassium carbonate in polar aprotic solvents, such as dimethylformamide, at ambient temperature. Mixed head monohalobutenedioates of Formula (I) (X =Br, Cl, F; h a =l; q=0; t=0) exist as 1 : 1 mixtures of regioisomers when synthesized by said process which comprises reacting two equivalents of a compound of Formula (III) with one equivalent of a compound of Formula (VII). However, mixed head monohalobutenedioates of Formula (I) (X 1= Br, Cl, F; h a =l; q=0; t=0) exist as pure regioisomers when synthesized by said processes comprising conversion of compounds of Formulae (la) to (lb) or conversion of compounds of Formulae (Ila) to (lib). Thus, the latter two processes are preferred methods for the preparation of mixed head monohalobutenedioates of Formula (I). Alkenedioate derivatives of Formula (I) and (II) may exist as E and Z geometric isomers; however, monohalogenated butenedioate analogs of Formula (I) preferentially exist as halofumarates such that the two ester carbonyl groups are oriented trans to one another. Compounds of Formula (I) may also exist as mixtures of diastereomers and one or more diastereomers may be separated from the mixture by conventional techniques; for example, chromatographic techniques. Compounds of Formulae (IV), (V) and (VI), diacid chloride derivatives of (VII) and compounds of Formula (VIII) are commercially available or may be prepared by published processes for the preparation of the same or structurally analogous compounds. Pure enantiomers of (V) are obtained by published asymmetric synthesis methods, known classical resolution techniques, or chiral preparative HPLC. Experimental Melting points are uncorrected. All reagent chemicals were used without purification. Analytical high performance liquid chromatography (HPLC) analyses were performed on a 4 x 250 mm 5m Si60 LiChrosorb column (E. Merck, Darmstadt, Germany) at a flow rate of 1.6 mL/min. The mobil phase consisted of 0-25% methanol (MeOH)/dichloromethane (CH 2 C1 2 ) mixtures containing 0.25 mL of methanesulfonic acid/L. Medium pressure liquid chromatography (MPLC) separations were performed on twin Porasil 15-20m cartridges (Waters/Millipore, Milford, MA, USA) eluting with 0-20% MeOH CH 2 C1 2 mixtures containing 0.25 mL of methanesulfonic acid L. Proton nuclear magnetic resonance ( HNMR) spectra of all products were consistent with the proposed structures. Positive ion flow injection electrospray mass spectra (MS) are reported in the form m/z (doubly charged positive ion, relative intensity). Elemental analyses were performed by Atlantic Microlab, Norcross, Georgia. Chlorofumaryl chloride was prepared by a reported procedure (Akhtar, M.; Botting, P.N.; Cohen, M.A. Tetrahedron 1987, 43, 5899-5908). 3,4-Dihydroisoquinoline derivatives were prepared by Bishler-Napieralski cyclization of the corresponding amides with phosphorous oxy chloride (Whaley, K. W.; Govindachari Org. Reactions 1951, 6, 74-150). Racemic 1,2,3,4-tetrahydroisoquinoline derivatives were prepared by reduction of their 3,4-dihydroisoquinoline precursors with sodium borohydride/methanol. N-Methylations of 1,2,3,4-tetrahydroisoquinoline derivatives were carried out with formaline/formic acid (Kaluszyner, A.; Galun A.B. J Org. Chem. 1961, 26, 3536-3537).

Biological Activity Cats were anesthetized with alpha-chloralose (80 mg/kg) and pentobarbital (10 mg/kg) i.p. See J.J. Savarese Anesthesia and Analgesia, Vol. 52, No. 6, November-December, (1973). Square- wave stimuli were applied at supramaximal voltage to the peroneal nerve at 0.15 Hz and the evoked twitches of the tibialis anterior muscle were recorded. Rhesus monkeys were anesthetized with ketamine (5 mg/Kg) and pentobarbitol (5 mg/Kg) given intramuscularly or intravenously. Anaesthesia was maintained with a mixture of halothane (0.25-0.75%)), nitrous oxide (60%) and oxygen (40%). The common peroneal nerve was stimulated supramaximally with square wave pulses of 0.2 m sec duration at a rate of 0.15 Hz. Twitch contractions were recorded via the tendon of the extensor digitorum muscle. In all animals, the trachea was intubated and ventilation was controlled at 12-15 ml/kg, 18-24 breaths per minute. Animals not receiving inhalation anesthetics were ventilated with room air. The left femoral vein and artery were cannulated for drug administration and for recording of arterial pressure, respectively. Compounds of Formula (I) listed in Tables 1 and 2 were administered intravenously. The ED 95 , i.e., the dose required to produce 95% block of the twitch response of compounds of Formula (I) are provided in Tables 1 and 2.
