Optimization of Orally Bioavailable PI3KdeltaInhibitors and Identification of Vps34 as a Key Selectivity Target

Optimization of a lead series of PI3Kdeltainhibitors based on a dihydroisobenzofuran core led to the identification of potent, orally bioavailable compound 19. Selectivity profiling of compound 19 showed similar potency for class III PI3K, Vps34, and PI3Kdelta, and compound 19 was not well-tolerated in a 7-day rat toxicity study. Structure-based design led to an improvement in selectivity for PI3Kdeltaover Vps34 and, a focus on oral phramacokinetics properties resulted in the discovery of compound 41, which showed improved toxicological outcomes at similar exposure levels to compound 19.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1055361-35-7, you can also check out more blogs about1055361-35-7

2-(2-arylidenehydrazinyl) thiazol-4(5H)-ones as epidermal growth factor receptor inhibitors: A combined quantitative structure activity relationship and pharmacophore study

2-(2-Arylidenehydrazinyl) thiazol-4(5H)-ones having epidermal growth factor receptor (EGFR) inhibitory activity were subjected to quantitative structure activity relationship (QSAR) (2 and 3 dimensional) analysis and pharmacophore study in the present work. The best 2 dimensional (2D) QSAR model had r2 (squared correlation coefficient), q2 (cross validated correlation coefficient) and pred_r2 (predictive correlation coefficient) values of 0.8630, 0.7652 and 0.9533 respectively with Partial least square regression (PLSR) analysis. This model showed that count of number of nitrogen atoms separated from oxygen atom by four bonds (T_N_O_4) and Radius Of Gyration (size descriptor) descriptors contribute positively and count of number of any atoms separated from carbon atom by four bonds (T_T_C_4) contributes inversely to the biological activity. The k-nearest neighbor (kNN) method produced a significant 3 dimensional (3D) QSAR model exhibiting q2 and pred_r2 values of 0.6615 and 0.8833 respectively. PLSR gave a significant 3D QSAR model having r2, q2 and pred_r2 values of 0.8449, 0.7816 and 0.7834 respectively. Both 3D QSAR models depict the need of less bulky substituents at R2 position while PLSR 3D QSAR model also portrays the need of more bulky substituent at R4 position. The identified common pharmacophore features are one aromatic (AroC) and three hydrogen bond acceptors (HAc) obtained from Molsign and Pharmagist approaches. The present work may be useful for further lead optimization and designing of potent anticancer agents.

In Silico Driven Design and Synthesis of Rhodanine Derivatives as Novel Antibacterials Targeting the Enoyl Reductase InhA

Here, we report on the design, synthesis, and biological evaluation of 4-thiazolidinone (rhodanine) derivatives targeting Mycobacterial tuberculosis (Mtb) trans-2-enoyl-acyl carrier protein reductase (InhA). Compounds having bulky aromatic substituents at position 5 and a tryptophan residue at position N-3 of the rhodanine ring were the most active against InhA, with IC50 values ranging from 2.7 to 30 muM. The experimental data showed consistent correlations with computational studies. Their antimicrobial activity was assessed against Mycobacterium marinum (Mm) (a model for Mtb), Pseudomonas aeruginosa (Pa), Legionella pneumophila (Lp), and Enterococcus faecalis (Ef) by using anti-infective, antivirulence, and antibiotic assays. Nineteen out of 34 compounds reduced Mm virulence at 10 muM. 33 exhibited promising antibiotic activity against Mm with a MIC of 0.21 muM and showed up to 89% reduction of Lp growth in an anti-infective assay at 30 muM. 32 showed high antibiotic activity against Ef, with a MIC of 0.57 muM.

Recent development of sulfonyl or sulfonamide hybrids as potential anticancer agents: A key review

Cancer is the second leading cause of death worldwide. There is always a huge demand for novel anticancer drugs and diverse new natural or synthetic compounds are developed continuously by scientists. Presently, a large number of drugs in clinical practice have showed pervasive side effect and multidrug resistance. Sulfonyl or sulfonamide hybrids became one of the most attractive subjects due to their broad spectrum of pharmacological activities. Sulfonyl hybrids were broadly explored for their anticancer activities and it was found that they possess minimum side effect along with multi-drug resistance activity. This review describes the most recent applications of sulfonyl hybrid analogues in anticancer drug discovery and further discusses the mechanistic insights, structure-activity relationships and molecular docking studies for the potent derivatives.

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.
