Design, synthesis, and anticancer potential of the enzyme (PARP-1) inhibitor with computational studies of new triazole, thiazolidinone, – thieno [2, 3-d] pyrimidinones

Background: Thienopyrimidine, triazole and thiazolidinone derivatives have recently gained attention due to their effective pharmacological activities. They show antioxidant, antitumor, antimicrobial, antiviral, anti-inflammatory and analgesic properties. Objective: Synthesis of new ethyl 2-amino-4-isopropyl-5-methylthiophene-3-carboxylate (2) was used as a starting material to produce 2-mercapto-methylthienopyrimidinone (3), (4) and 2- hydrazinyl-methylthienopyrimidinone (5), through high yields and evaluating anticancer activities. Methods: A series of novel Schiff?s bases (6-9) were produced after treatment of (5) with aldehydes. Triazolopyrimidinones (6a, 7a, 8a, 9a) were produced from cyclization of benzylidene (6-9) using Br2 / AcOH or dry pyridine /Ac2O. Thiazolidinones (6b, 7b, 8b, 9b) were synthesized from benzylidene (6-9) with mercaptoacetic acid. Results: All the compounds were synthesized in good yields (55-85%) in a regularly actual system under mild condition. The new compounds have been established by means of diverse spectroscopic ways as IR, NMR and MS. The newly synthesized compounds were evaluated for their antiproliferative activity against the breast MCF-7 carcinoma cell line. Compound (7) showed promising anticancer activity with IC50 of 6.9 muM, and 40.8% of antioxidant effect as DPPH inhibition. Molecular docking of (7) showed deltaG values of-20.54 kcal/ mol and -25.60 kcal/ mol. Molecular dynamics simulation of (7) in complex with PARP-1 revealed RMSD of 3.00 a. Conclusion: The QSAR study confirmed the presence of a relationship between anticancer activity and subdivided surface area descriptors with coefficient r2 = 0.98 with high predictive power.

Synthesis and Biological Evaluation of Novel 5-Oxo-1-Phenylpyrrolidine-3-Carboxylic Acid Analogs

A number of 5-oxo-1-phenyl-4-(substituted methyl) pyrrolidine-3-carboxylic acid derivatives bearing pyrrolidine ring and methylamino residues in their structure were synthesized as potential antibacterial drugs. The chemical structures of all the compounds were established by their UV-Vis absorption spectroscopy, IR, 1 H, 13 C NMR and mass spectroscopy. The in vitro antibacterial screening of all novel compounds was done against gram-positive Staphylococcus aureus, Bacillus subtilis and gram-negative Pseudomonas aeruginosa. The results revealed that compounds 5d, e, f and g showed moderate to good activity against the tested microbes.

Penultimate group effects in free radical telomerizations of acrylamides

The telomerization of several acrylamides, most containing chiral auxiliary groups, was investigated. The first-formed stereogenic center in the n = 2 telomer (the penultimate center) has a significant effect on the configuration of the second (ultimate) center in the product. The penultimate chiral center of oxazolidine-derived acrylamides directs the configuration of the ultimate center such that the erythro n = 2 product is preferred. Sultam-substituted acrylamides preferentially lead, on the other hand, to threo products or give products with little stereoselectivity.

Acid-Catalyzed Synthesis of Thiazolidin-4-ones

A two-steps synthesis of thiazolidin-4-ones, from alpha-tetralone 6 or thiochroman-4-one 7, catalyzed by acids is described. The reactions of alpha-tetralone 6 or thiochroman-4-one 7, with substituted thiosemicarbazides, under AcOH or heteropolyacid (HPAs) catalysis afford thiosemicarbazones 8 and 9 in excellent yields. Condensations of the previous compounds 8 and 9 with alpha-bromoester, under sulfuric acid or heteropolyacid catalysis, yield the corresponding thiazolidin-4-ones 10 and 11.

Thiazolidine prodrugs as protective agents against gamma-radiation-induced toxicity and mutagenesis in V79 cells

Representatives of two classes of thiazolidine prodrug forms of the well-known radioprotective agents L-cysteine, cysteamine, and 2-[(aminopropyl)amino]ethanethiol (WR-1065) were synthesized by condensing the parent thiolamine with an appropriate carbonyl donor. Inherent toxicity of the prodrugs was assessed in V79 cells using a clonogenic survival assay. Protection against radiation-induced cell death was measured similarly after exposure to 0-8 Gy gamma (137Cs) radiation. Antimutagenic activity was determined at the hypoxanthine-guanine phosphoribosyltransferase (HGPRT) locus. All thiazolidine prodrugs exhibited less toxicity than their parent thiolamines, sometimes dramatically so. Protection against radiation-induced cell death was observed for the 2-alkylthiazolidine, 2(R,S)-D-ribo-(1?,2?,3?,4?-tetrahydroxybutyl) thiazolidine (RibCyst), which produced a protection factor at 8 Gy of 1.8; the cysteine analogue, 2(R,S)-D-ribo-(1?,2?,3?,4?-tetrahydroxybutyl) thiazolidine-4(R)-carboxylic acid (RibCys), was less active. RibCyst also exhibited excellent antimutational activity, rivaling that of WR-1065. The 2-oxothiazolidine analogues showed little activity in either determination under the conditions tested, perhaps due to their enhanced chemical and biochemical stability.

Discovery of potent HIV integrase inhibitors active against raltegravir resistant viruses

A series of novel HIV integrase inhibitors active against rategravir resistant strains are reported. Initial SAR studies revealed that activities against wild-type virus were successfully maintained at single digit nanomolar level with a wide range of substitutions. However, inclusion of nitrogen-based cyclic substitutions was crucial for achieving potency against mutant viruses. Several compounds with excellent activities against wild-type virus as well as against the viruses with the mutations Q148H/G140S or N155H/E92Q were reported.

Quinine conjugates and quinine analogues as potential antimalarial agents

Malaria is a tropical disease, prevalent in Southeast Asia and Africa, resulting in over half a million deaths annually; efforts to develop new antimalarial agents are therefore particularly important. Quinine continues to play a role in the fight against malaria, but quinoline derivatives are more widely used. Drugs based on the quinoline scaffold include chloroquine and primaquine, which are able to act against the blood and liver stages of the parasite’s life cycle. The purpose of this review is to discuss reported biologically active compounds based on either the quinine or quinoline scaffold that may have enhanced antimalarial activity. The review emphasises hybrid molecules, and covers advances made in the last five years. The review is divided into three sections: modifications to the quinine scaffold, modifications to aminoquinolines and finally metal-containing antimalarial compounds.
