## Title
Apoptosis-inducing agents for the treatment of cancer and immune and autoimmune diseases

## Abstract

Disclosed are compounds which inhibit the activity of anti-apoptotic Bcl-2 proteins, compositions containing the compounds and methods of treating diseases during which is expressed anti-apoptotic Bcl-2 protein.

## Background
This application claims priority to U.S. Provisional Application Ser. No. 61/348422 filed May 26, 2010, which is incorporated by reference in its entirety.


FIELD OF THE INVENTION
This invention pertains to water soluble compounds which inhibit the activity of Bcl-2 anti-apoptotic proteins, compositions containing the compounds, and methods of treating diseases during which anti-apoptotic Bcl-2 proteins are expressed.
BACKGROUND OF THE INVENTION
Anti-apoptotic Bcl-2 proteins are associated with a number of diseases. There is therefore an existing need in the therapeutic arts for compounds which inhibit the activity of anti-apoptotic Bcl-2 proteins.
Overexpression of Bcl-2 proteins correlates with resistance to chemotherapy, clinical outcome, disease progression, overall prognosis or a combination thereof in various cancers and disorders of the immune system.
Involvement of Bcl-2 proteins in bladder cancer, brain cancer, breast cancer, bone marrow cancer, cervical cancer, chronic lymphocytic leukemia, colorectal cancer, esophageal cancer, hepatocellular cancer, lymphoblastic leukemia, follicular lymphoma, lymphoid malignancies of T-cell or B-cell origin, melanoma, myelogenous leukemia, myeloma, oral cancer, ovarian cancer, non-small cell lung cancer, prostate cancer, small cell lung cancer, spleen cancer, and the like is described in commonly-owned PCT US 2004/36770, published as WO 2005/049593, and PCT US 2004/37911, published as WO 2005/024636.
Involvement of Bcl-2 proteins in immune and autoimmune diseases is described in Current Allergy and Asthma Reports 2003, 3, 378-384; British Journal of Haematology 2000, 110(3), 584-90; Blood 2000, 95(4), 1283-92; and New England Journal of Medicine 2004, 351(14), 1409-1418. Involvement of Bcl-2 proteins in arthritis is disclosed in commonly-owned U.S. Provisional Patent Application Ser. No. 60/988,479. Involvement of Bcl-2 proteins in bone marrow transplant rejection is disclosed in commonly-owned U.S. patent application Ser. No. 11/941,196.
Solubility influences the oral absorption of pharmaceuticals. Drugs with poor dissolution rates are associated with low and variable bioavailability, higher potential for food effects, and inability to deliver high doses for toxicity studies, and difficulty in developing parenteral formulations. Therefore, increasing the solubility of compounds may alleviate these risks associated with low solubility and, moreover, constitute an advantage.
SUMMARY OF THE INVENTION
One embodiment of this invention, therefore, pertains to compounds or therapeutically acceptable salts, which are useful as selective inhibitors of one or more than one anti-apoptotic protein family member, the compounds having Formula (I), (II), or (III)

Compounds
Geometric isomers may exist in the present compounds. Compounds of this invention may contain carbon-carbon double bonds or carbon-nitrogen double bonds in the E or Z configuration, wherein the term “E” represents higher order substituents on opposite sides of the carbon-carbon or carbon-nitrogen double bond and the term “Z” represents higher order substituents on the same side of the carbon-carbon or carbon-nitrogen double bond as determined by the Cahn-Ingold-Prelog Priority Rules. The compounds of this invention may also exist as a mixture of “E” and “Z” isomers. Substituents around a cycloalkyl or heterocycloalkyl are designated as being of cis or trans configuration. Furthermore, the invention contemplates the various isomers and mixtures thereof resulting from the disposal of substituents around an adamantane ring system. Two substituents around a single ring within an adamantane ring system are designated as being of Z or E relative configuration. For examples, see C. D. Jones, M. Kaselj, R. N. Salvatore, W. J. le Noble J. Org. Chem. 1998, 63, 2758-2760 and E. L. Eliel, and S. H. Wilen. (1994) Stereochemistry of Organic Compounds. New York, N.Y.: John Wiley & Sons, Inc.
Compounds of this invention contain asymmetrically substituted carbon atoms in the R or S configuration, in which the terms “R” and “S” are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-10. Compounds having asymmetrically substituted carbon atoms with equal amounts of R and S configurations are racemic at those carbon atoms. Atoms with an excess of one configuration over the other are assigned the configuration present in the higher amount, preferably an excess of about 85%-90%, more preferably an excess of about 95%-99%, and still more preferably an excess greater than about 99%. Accordingly, this invention includes racemic mixtures, relative and absolute stereoisomers, and mixtures of relative and absolute stereoisomers.
Compounds of this invention containing NH, C(O)OH, OH or SH moieties may have attached thereto prodrug-forming moieties. The prodrug-forming moieties are removed by metabolic processes and release the compounds having the freed hydroxyl, amino or carboxylic acid in vivo. Prodrugs are useful for adjusting such pharmacokinetic properties of the compounds as solubility and/or hydrophobicity, absorption in the gastrointestinal tract, bioavailability, tissue penetration, and rate of clearance.
Isotope Enriched or Labeled Compounds
Compounds of the invention can exist in isotope-labeled or -enriched form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes can be radioactive or non-radioactive isotopes. Isotopes of atoms such as hydrogen, carbon, phosphorous, sulfur, fluorine, chlorine, and iodine include, but are not limited to 2H, 3H, 13C, 14C, 15N, 18O, 32P, 35S, 18F, 36Cl, and 125I. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention.
In another embodiment, the isotope-labeled compounds contain deuterium (2H), tritium (3H) or 14C isotopes. Isotope-labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotope-labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples disclosed herein and Schemes by substituting a readily available isotope-labeled reagent for a non-labeled reagent. In some instances, compounds may be treated with isotope-labeled reagents to exchange a normal atom with its isotope, for example, hydrogen for deuterium can be exchanged by the action of a deuteric acid such as D2SO4/D2O. In addition to the above, relevant procedures and intermediates are disclosed, for instance, in Lizondo, J et al., Drugs Fut, 21(11), 1116 (1996); Brickner, S Jet al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al., Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat. Nos. 7,538,189; 7,534,814; 7,531,685; 7,528,131; 7,521,421; 7,514,068; 7,511,013; and US Patent Application Publication Nos. 20090137457; 20090131485; 20090131363; 20090118238; 20090111840; 20090105338; 20090105307; 20090105147; 20090093422; 20090088416; and 20090082471, the methods are hereby incorporated by reference.
The isotope-labeled compounds of the invention may be used as standards to determine the effectiveness of Bcl-2 inhibitors in binding assays. Isotope containing compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the nonisotope-labeled parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).
In addition, non-radio active isotope containing drugs, such as deuterated drugs called “heavy drugs,” can be used for the treatment of diseases and conditions related to Bcl-2 activity. Increasing the amount of an isotope present in a compound above its natural abundance is called enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. Replacement of up to about 15% of normal atom with a heavy isotope has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. New York Acad. Sci 1960 84: 736; Czakja D Metal., Am. J. Physiol. 1961 201: 357). Acute replacement of as high as 15%-23% in human fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).
Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one important exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. Accordingly, the incorporation of an isotope at a site of metabolism or enzymatic transformation will slow said reactions potentially altering the pharmcokinetic profile or efficacy relative to the non-istopic compound.
One embodiment of this invention, therefore, pertains to compounds or therapeutically acceptable salts, which are useful as selective inhibitors of one or more than one anti-apoptotic protein family member, the compounds having Formula (I), (II), or (III)

BiTE antibodies are bi-specific antibodies that direct T-cells to attack cancer cells by simultaneously binding the two cells. The T-cell then attacks the target cancer cell. Examples of BiTE antibodies include adecatumumab (Micromet MT201), blinatumomab (Micromet MT103) and the like. Without being limited by theory, one of the mechanisms by which T-cells elicit apoptosis of the target cancer cell is by exocytosis of cytolytic granule components, which include perforin and granzyme B. In this regard, Bcl-2 has been shown to attenuate the induction of apoptosis by both perforin and granzyme B. These data suggest that inhibition of Bcl-2 could enhance the cytotoxic effects elicited by T-cells when targeted to cancer cells (V. R. Sutton, D. L. Vaux and J. A. Trapani, J. of Immunology 1997, 158 (12), 5783).
SiRNAs are molecules having endogenous RNA bases or chemically modified nucleotides. The modifications do not abolish cellular activity, but rather impart increased stability and/or increased cellular potency. Examples of chemical modifications include phosphorothioate groups, 2′-deoxynucleotide, 2′-OCH3-containing ribonucleotides, 2′-F-ribonucleotides, 2′-methoxyethyl ribonucleotides, combinations thereof and the like. The siRNA can have varying lengths (e.g., 10-200 bps) and structures (e.g., hairpins, single/double strands, bulges, nicks/gaps, mismatches) and are processed in cells to provide active gene silencing. A double-stranded siRNA (dsRNA) can have the same number of nucleotides on each strand (blunt ends) or asymmetric ends (overhangs). The overhang of 1-2 nucleotides can be present on the sense and/or the antisense strand, as well as present on the 5′- and/or the 3′-ends of a given strand. For example, siRNAs targeting Mcl-1 have been shown to enhance the activity of ABT-263, (i.e., N-(4-(4((2-(4-chlorophenyl)-5,5-dimethyl-1-cyclohex-1-en-1-yl)methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(morpholin-4-yl)-1-((phenylsulfanyl)methyl)propyl)amino)-3-((trifluoromethyl)sulfonyl)benzenesulfonamide) or ABT-737 (i.e., N-(4-(4-((4′-chloro(1,1′-biphenyl)-2-yl)methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(dimethylamino)-1-((phenylsulfanyl)methyl)propyl)amino)-3-nitrobenzenesulfonamide) in multiple tumor cell lines (Tse et. al, Cancer Research 2008, 68(9), 3421 and references therein).
Multivalent binding proteins are binding proteins comprising two or more antigen binding sites. Multivalent binding proteins are engineered to have the three or more antigen binding sites and are generally not naturally occurring antibodies. The term “multispecific binding protein” means a binding protein capable of binding two or more related or unrelated targets. Dual variable domain (DVD) binding proteins are tetravalent or multivalent binding proteins binding proteins comprising two or more antigen binding sites. Such DVDs may be monospecific (i.e., capable of binding one antigen) or multispecific (i.e., capable of binding two or more antigens). DVD binding proteins comprising two heavy chain DVD polypeptides and two light chain DVD polypeptides are referred to as DVD Ig's. Each half of a DVD Ig comprises a heavy chain DVD polypeptide, a light chain DVD polypeptide, and two antigen binding sites. Each binding site comprises a heavy chain variable domain and a light chain variable domain with a total of 6 CDRs involved in antigen binding per antigen binding site. Multispecific DVDs include DVD binding proteins that bind DLL4 and VEGF, or C-met and EFGR or ErbB3 and EGFR.

Electrospray mass-spectra (ESI-MS) were recorded on Finnigan SSQ7000 (Finnigan Corp., San Jose, Calif.) in both positive and negative ion mode.
General Procedure For Solid-Phase Peptide Synthesis (SPPS)
Peptides were synthesized with, at most, 250 μmol preloaded Wang resin/vessel on an ABI 433A peptide synthesizer using 250 μmol scale FastmocTM coupling cycles. Preloaded cartridges containing 1 mmol standard Fmoc-amino acids, except for the position of attachment of the fluorophore, where 1 mmol Fmoc-Lys(Mtt)-OH was placed in the cartridge, were used with conductivity feedback monitoring. N-terminal acetylation was accomplished by using 1 mmol acetic acid in a cartridge under standard coupling conditions.
Removal of 4-Methyltrityl (Mtt) From Lysine
The resin from the synthesizer was washed thrice with dichloromethane and kept wet. 150 mL of 95:4:1 dichloromethane:triisopropylsilane:trifluoroacetic acid was flowed through the resin bed over 30 minutes. The mixture turned deep yellow then faded to pale yellow. 100 mL of N,N-dimethylformamide was flowed through the bed over 15 minutes. The resin was then washed thrice with N,N-dimethylformamide and filtered. Ninhydrin tests showed a strong signal for primary amine.
Resin Labeling With 6-Carboxyfluorescein-NHS (6-FAM-NHS)
The resin was treated with 2 equivalents 6-FAM-NHS in 1% DIEA/N,N-dimethylformamide and stirred or shaken at ambient temperature overnight. When complete, the resin was drained, washed thrice with N,N-dimethylformamide, thrice with (1× DCM and 1× methanol) and dried to provide an orange resin that was negative by ninhydrin test.
General Procedure for Cleavage and Deprotection of Resin-Bound Peptide
Peptides were cleaved from the resin by shaking for 3 hours at ambient temperature in a cleavage cocktail consisting of 80% TFA, 5% water, 5% thioanisole, 5% phenol, 2.5% TIS, and 2.5% EDT (1 mL/0.1 g resin). The resin was removed by filtration and rinsing twice with TFA. The TFA was evaporated from the filtrates, and product was precipitated with ether (10 mL/0.1 g resin), recovered by centrifugation, washed twice with ether (10 mL/0.1 g resin) and dried to give the crude peptide.
General Procedure for Purification of Peptides
The crude peptides were purified on a Gilson preparative HPLC system running Unipoint® analysis software (Gilson, Inc., Middleton, Wis.) on a radial compression column containing two 25×100 mm segments packed with Delta-PakTM C18 15 μm particles with 100 Å pore size and eluted with one of the gradient methods listed below. One to two milliliters of crude peptide solution (10 mg/mL in 90% DMSO/water) was purified per injection. The peaks containing the product(s) from each run were pooled and lyophilized. All preparative runs were run at 20 mL/min with eluents as buffer A: 0.1% TFA-water and buffer B: acetonitrile.
General Procedure for Analytical HPLC
Analytical HPLC was performed on a Hewlett-Packard 1200 series system with a diode-array detector and a Hewlett-Packard 1046A fluorescence detector running HPLC 3D CHEMSTATION software version A.03.04 (Hewlett-Packard. Palo Alto, Calif.) on a 4.6×250 mm YMC column packed with ODS-AQ 5 μm particles with a 120 Å pore size and eluted with one of the gradient methods listed below after preequilibrating at the starting conditions for 7 minutes. Eluents were buffer A: 0.1% TFA-water and buffer B: acetonitrile. The flow rate for all gradients was 1 mL/min.
F-Bak: Peptide Probe Acetyl-GQVGRQLAIIGDK(6-FAM)INR-NH, (SEQ ID NO:1)
Fmoc-Rink amide MBHA resin was extended using the general peptide synthesis procedure to provide the protected resin-bound peptide (1.020 g). The Mtt group was removed, labeled with 6-FAM-NHS and cleaved and deprotected as described hereinabove to provide the crude product as an orange solid (0.37 g). This product was purified by RP-HPLC. Fractions across the main peak were tested by analytical RP-HPLC, and the pure fractions were isolated and lyophilized, with the major peak providing the title compound (0.0802 g) as a yellow solid; MALDI-MS m/z=2137.1 [(M+H)+].
Alternative Synthesis of Peptide Probe F-Bak: Acetyl-GQVGRQLAIIGDK(6-FAM)INR-NH, (SEQ ID NO:1)
The protected peptide was assembeled on 0.25 mmol Fmoc-Rink amide MBHA resin (Novabiochem) on an Applied Biosystems 433A automated peptide synthesizer running FASTMOCTM coupling cycles using pre-loaded 1 mmol amino acid cartridges, except for the fluorescein(6-FAM)-labeled lysine, where 1 mmol Fmoc-Lys(4-methyltrityl) was weighed into the cartridge. The N-terminal acetyl group was incorporated by putting 1 mmol acetic acid in a cartridge and coupling as described hereinabove. Selective removal of the 4-methyltrityl group was accomplished with a solution of 95:4:1 DCM:TIS:TFA (v/v/v) flowed through the resin over 15 minutes, followed by quenching with a flow of dimethylformamide.
Single-isomer 6 carboxyfluorescein-NHS was reacted with the lysine side-chain in 1% DIEA in N,N-dimethylformamide and confirmed complete by ninhydrin testing. The peptide was cleaved from the resin and side-chains deprotected by treating with 80:5:5:5:2.5:2.5 TFA/water/phenol/thioanisole/triisopropylsilane: 3,6-dioxa-1,8-octanedithiol (v/v/v/v/v v), and the crude peptide was recovered by precipitation with diethyl ether. The crude peptide was purified by reverse-phase high-performance liquid chromatography, and its purity and identity were confirmed by analytical reverse-phase high-performance liquid chromatography and matrix-assisted laser-desorption mass-spectrometry (m/z =2137.1 ((M+H)+)).
Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay
Representative compounds were serially diluted in dimethyl su foxide (DMSO) starting at 50 μM (2×starting concentration; 10% DMSO) and 10 μL were transferred into a 384-well plate. Then 10 μL of a protein/probe/antibody mix was added to each well at final concentrations listed in TABLE 1. The samples are then mixed on a shaker for 1 minute and incubated for an additional 3 hours at room temperature. For each assay, the probe/antibody and protein/probe/antibody were included on each assay plate as negative and positive controls, respectively. Fluorescence was measured on the ENVISION plate reader (Perkin Elmer) using a 340/35 nm excitation filter and 520/525 (F-Bak peptide) and 495/510 nm (Tb-labeled anti-Histidine antibody) emission filters. Inhibition constants (Ki) are shown in TABLE 2 below and were determined using Wang's equation (Wang Z.-X. An Exact Mathematical Expression For Describing Competitive Binding Of Two Different Ligands To A Protein Molecule. FEBS Lett. 1995, 360:111-4).

Inhibition constants (Ki) for compounds according to the invention are shown in TABLE 2 below. Where the Ki for a compound is represented as “>” (greater than) a certain numerical value, it is intended to mean that the binding affinity value is greater than the limits of detection of the assay used. Where the Ki for a compound is represented as “<” (less than) a certain numerical value, it is intended to mean that the binding affinity value is lower than the limit of detection of the assay used.

The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein. So a large Ki value indicates a low binding affinity and a small Ki value indicates a high binding affinity.
The data in TABLE 2 shows inhibition constants for the inhibition of a Bak BH3 peptide probe to Bcl-2 protein and indicate that compounds according to the invention have high binding affinities for anti-apoptotic Bcl-2 protein. The compounds are therefore expected to have utility in treatment of diseases during which anti-apoptotic Bcl-2 protein is expressed.
RS4;11 Cell Viability Assay
The acute lymphoblastic leukemia (ALL) cell line RS4;11 was used as the primary human cell line to assess the cellular activity of Bcl-2 selective agents in vitro and their efficacy in vivo. Previous studies have shown by BH3 profiling, a mitochondrial assay that classifies blocks in the intrinsic apoptotic pathway, that RS4;11 cells were highly dependant on BCL-2 for survival and sensitive to the Bcl-2 family member inhibitor ABT-737 (Blood, 2008, Vol. 111, 2300-2309). The prevalence of Bcl-2 complexed to the proapoptotic BH3 protein Bim in RS4;11 suggests that these cells are “primed” or more susceptible to cell death by antagonism of the antiapoptotic protein Bcl-2 for which they depend on for survival.
RS4;11 cells were cultured in RPMI-1640 supplemented with 2 mM L-glutamine, 10% FBS, 1 mM sodium pyruvate, 2 mM HEPES, 1% penicillin/streptomycin (Invitrogen), 4.5 g/L glucose and maintained at 37 C containing 5% CO2. To test for the cellular activity of compounds in vitro, cells were treated at 50,000 cells per well in 96-well microtiter plates in the presence of 10% human serum for 48 hours in a humidified chamber with 5% CO2. Cell cytotoxicity EC50 values were assessed using CellTiter Glo (Promega) according to the manufacturer's recommendations. The EC50 values were determined as a percentage of viable cells following treatment compared to the untreated control cells.

TABLE 3 shows the utility of compounds having Formula I to functionally inhibit anti-apoptotic Bcl-2 protein in a cellular context. The acute lymphoblastic leukemia (ALL) cell line RS4;11 has been shown by BH3 profiling, a mitochondrial assay that classifies blocks in the intrinsic apoptotic pathway, to be highly dependant on Bcl-2 for survival and is sensitive to the Bcl-2 family member inhibitor ABT-737 (Blood, 2008, Vol. 111, 2300-2309). The ability of compounds to kill RS4;11 cells is a direct measure of the compounds ability to inhibit anti-apoptotic Bcl-2 protein function. Compounds of Formula I are very effective in killing RS4;11 cells as demonstrated by low EC50 values.
The neutral form of compounds are generally and considerably more permeable than the charged form (Chakrabarti, A. C.; Clark-Lewis, I.; Harrigan, P. R.; Cullis, P. R. Biophysical Journal. 1992, 61, 228-234). Furthermore, the presence of a charged residue can result in a permeability rate of up to 1010 times slower than that observed for the corresponding neutral species (Ellens, H.; Eddy, E. P.; Lee, C.; Dougherty, P.; Lago, A.; Xiang, J.; Elliot, J. D.; Cheng, H.; Ohlstein, E.; Smith, P. Advanced Drug Delivery Reviews. 1997, 23, 99-109). Compounds of this invention contain a phosphate group, which is expected to be negatively charged at physiological pH, in addition to an acylsufonamide moiety, which is also expected to be negatively charged at physiological pH. It is therefore expected that compounds of the invention, which contain multiple negative charges at physiological pH, would not be able to penetrate the cell membrane of RS4;11 cells and induce apoptosis, or programmed cell death. As demonstrated in Table 3, compounds of this invention are unexpectedly capable of penetrating the cell membrane and inducing programmed cell death.

The vial was sealed with cap and wrapped with aluminum foil, then tumbled in a 25° C. or 37° C. water bath as appropriate. When equilibration was completed, the samples were removed from the water bath and the final pH's were measured. The suspensions were filtered through 4 mm, 0.2 μm Millex-LG syringe filters (hydrophilic PTFE membrane, Millipore, Lot N9JN70696). Each filter was used only for one sample and the first three droplets were discarded. The filtrate was assayed after appropriate dilution with the same solvent as used for stock solution. Three replicates were prepared. The concentration of the sample was calculated against the calibration curve for the compound.
