Synthesis of new chiral sulfinyldiacetic acid derivatives and attempt at chemoselective asymmetric pummerer reaction

(RS)-1 (85% ee) was prepared by utilizing a porcin pancreatic lipase-promoted hydrolysis of sulfinyldiacetic acid dimethyl ester (8) which was derived from thiodiacetic acid (7). (RS)-1 (99% ee) and (S S)-1 (99% ee) were readily obtained by methanolysis of (R S,S)-12 and (SS,S)-12 with MeONa in MeOH. (R S,S)-12 and (SS,S)-12 were furnished by chromatographic separation of the diastereomeric mixture, obtained by oxidation of thiodiacetic mono-carboxylic acid (11) with 30% H2O2 followed by dehydrative condensation of the resultant sulfinyldiacetic mono-carboxylic acid with 4(S)-isopropyl-1,3-thiazolidine-2-thione. (RS)-1 (99% ee) was successively treated with (TMS)2NLi, Ac2O, and TMSOTf to give a major chiral-3 product in 75% ee and in a highly chemoselective manner (chiral-3:chiral-2593:7).

Insilico proportional molecular docking study and analysis of insulinotropic activity of TZD derivatives by PPARgamma activation

Purpose: The thiazolidinediones (TZDs) have become one of the most commonly approved classes of medication for type 2 diabetes. In addition to glucose control, the TZDs have a number of pleiotropic effects risk factors for diabetes. Method: In the present studies, we investigate and assess the insulinotropic prospective using binding energy and pharmacological interaction of TZD derivatives using insilico proportional molecular docking relation approach against roziglitazone and to investigate the mechanism of action of TZD derivatives as a hypoglycemic agent, both in-vivo and in-vitro experiments were conducted. Investigations were conducted on the intestinal level by delaying or inhibiting glucose absorption, the peripheral level on insulin-sensitive tissues by facilitating the entry of glucose into cells such as muscle, and the pancreatic level by stimulating insulin secretion. Result: In this series, the most potent compounds were 6a and 6b having methoxy group at C5 position of TZD ring. Conclusion: 5-(substituted benzylidene)-2-(4-chloro-2-fluoro-5-methoxybenzylidene) hydrazono) thiazolidin-4-one have shown better antidiabetic activity. However, clinical trials with standardized extracts and uniform protocols have been with experimental animals and validated TZD derivatives clinical applicability as an antidiabetic agent. The outcomes of such studies may be useful for the clinical applications in humans and may open up a new therapeutic avenue.

Pyridine and pyrimidine analogs of acetaminophen as inhibitors of lipid peroxidation and cyclooxygenase and lipoxygenase catalysis

Herein we report an investigation of the efficacy of pyridine and pyrimidine analogs of acetaminophen (ApAP) as peroxyl radical-trapping antioxidants and inhibitors of enzyme-catalyzed lipid peroxidation by cyclooxygenases (COX) and lipoxygenases (LOX). In inhibited autoxidations we find that ApAP, the common analgesic and antipyretic agent, is a very good antioxidant with a rate constant for reaction with peroxyl radicals (k inh = 5 ¡Á 105 M-1 s-1) that is higher than many widely-used phenolic antioxidants, such as the ubiquitous butylated hydroxytoluene (BHT). This reactivity is reduced substantially upon incorporation of nitrogen into the phenolic ring, owing to an increase in the O-H bond dissociation enthalpy of pyridinols and pyrimidinols with respect to phenols. Incorporation of nitrogen into the phenolic ring of ApAP was also found to decrease its efficacy as an inhibitor of prostaglandin biosynthesis by ovine COX-1 (oCOX-1). This is explained on the basis of an increase in its oxidation potential and its reduced reactivity as a reducing co-substrate of the peroxidase protoporphyrin. In contrast, the efficacy of ApAP as an inhibitor of lipid hydroperoxide biosynthesis by soybean LOX-1 (sLOX-1) increased upon incorporation of nitrogen into the ring, suggesting a different mechanism of inhibition dependent on the acidity of the phenolic O-H which may involve chelation of the catalytic non-heme iron atom. The greater stability of the 3-pyridinols and 5-pyrimidinols to air oxidation as compared to phenols allowed us to evaluate some electron-rich pyridinols and pyrimidinols as inhibitors of oCOX-1 and sLOX-1. While the pyridinols had the best combination of activities as antioxidants and inhibitors of oCOX-1 and sLOX-1, they were found to be more toxic than ApAP in preliminary assays in human hepatocellular carcinoma (HepG2) cell culture. The pyrimidinols, however, were up to 17-fold more reactive to peroxyl radicals and up to 25-fold better inhibitors of prostaglandin biosynthesis than ApAP, with similar cytotoxicities to HepG2 cells at high levels of exposure.

Chiral ferrocenylthiazolidines, new ligands for palladium complexes

The reaction of ferrocene with methyl or ethyl esters of L-cysteine in the presence of paraformaldehyde is studied. This process yields the optically pure derivatives: methyl or ethyl (R)-3-(ferrocenylmethyl)thiazolidine-4-carboxylates (1a or 1b), together with the corresponding N,N-bisthiazolidine derivatives (2a or 2b). When the reaction was carried out using the ethyl ester of L-cysteine, small amounts (ca. 9%) of the 1,1′-disubstituted ferrocene derivative (3b) were also isolated. The reactivity of compounds 1 versus palladium(II) species is studied, and has allowed us to isolate and characterise: [Pd(eta3-C3H5)Br(1a)] (4a) and [Pd(eta3-C3H5)Br(1b)] (4b), in which the ferrocenyl ligand behaves as a monodentate S-donor group. Compounds 4 evolve in the presence of dimethylsulfoxide to produce: [Pd(eta1-C3H5)Br(1)(dmso)] (5) in which the palladium(II) is bound to the terminal carbon of the C3H5 group. The reactivity of ligands 1 with Na2[PdCl4] is also reported and has allowed us to isolate the dinuclear compounds [Pd2Cl4(mu-1a)2] (6a) and [Pd2Cl4(mu-1b)2] (6b)] in which the thiazolidine behaves as a bridging (N,S) donor group.

Synthesis and pharmacological evaluation of some 2-(4-isobutylphenyl)-N-(4-oxo-2-arylthiazolidin-3-yl) propanamides

Some derivatives of ibuprofen bearing 4H-thiazolidin-4-one moiety were synthesized from ibuprofen and studied for their pharmacological activities. Methyl ester of ibuprofen I was synthesized from ibuprofen and then converted to hydrazide II with the reaction of hydrazine hydrate. Hydrazide of ibuprofen then reacted with aromatic aldehydes in the presence of glacial acetic acid to yield the hydrazones III which on reaction with thioglycolic acid and dimethyl formamide in presence of catalytic amount of anhydrous zinc chloride furnished the title compounds IV. The structures of synthesized compounds were elucidated mainly by spectral evidence. All the synthesized title compounds were screened for their anti-inflammatory activity. Title compounds were also studied for their ulcerogenic potential. The compounds exhibited moderate to significant activities.

A novel series of IKKbeta inhibitors part I: Initial SAR studies of a HTS hit

A novel series of (E)-1-((2-(1-methyl-1H-imidazol-5-yl) quinolin-4-yl) methylene) thiosemicarbazides was discovered as potent inhibitors of IKKbeta. In this Letter we document our early efforts at optimization of the quinoline core, the imidazole and the semithiocarbazone moiety. Most potency gains came from substitution around the 6- and 7-positions of the quinoline ring. Replacement of the semithiocarbazone with a semicarbazone decreased potency but led to some measurable exposure.

Synthesis of new C3 symmetric amino acid- and aminoalcohol-containing chiral stationary phases and application to HPLC enantioseparations

We recently reported a new C3-symmetric (R)-phenylglycinol N-1,3,5-benzenetricarboxylic acid-derived chiral high-performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N-3,5-dintrobenzoyl (DNB) (R)-phenylglycinol-derived CSP. Over a decade ago, (S)-leucinol, (R)-phenylglycine, and (S)-leucine derivatives were used as the starting materials of 3,5-DNB-based Pirkle-type CSPs for chiral separation. In this study, three new C3-symmetric CSPs (CSP 2, 3, and 4) were prepared by combining the ideas and results mentioned above. Here we describe the synthetic procedures and applications of the new C3-symmetric CSPs (CSP 2?CSP 4).
