Synthesis and in vitro anti-breast cancer evaluation of some novel benzimidazole ?pyridine conjugates

A new series of benzimidazole bearing pyridine derivatives were synthesized by condensation of 1,2-phenylenediamine with 2-oxo-1,2-dihydro-pyridine-3-carboxylic acid derivative 2 in phosphoric acid to give 3-(1Hbenzo[ d]imidazol-2-yl)-pyridin-2(1H)-one derivative 3. Compound 3 on further reaction with a mixture of phosphorus oxychloride and phosphorus pentachloride gave 2-(2-chloro-) pyridin-3-yl)-1H-benzo[d] imidazole derivative 4. Moreover, 4 were reacted with different amines to give 3-(1H-benzo[d]imidazol-2-yl)-N-(substituted) pyridin-2-amine derivatives 5a-c. Meanwhile, N-(N-(substituted) sulfamoyl) pyridin-3-yl)-1H-benzo[d]imidazole-1-carboxamide derivatives 7a,b were synthesized by reaction of 5c with chlorosulfonyl isocyanate to give 2-(pyridin-3-yl)-1H-benzo [d]imidazole-1-carbonyl) sulfamoyl chloride derivative followed by reaction of the latter with different amines. On the other hand, upon treatment compound 4 with hydrazine hydrate gave the hydrazide derivative 8. The reaction of compound 8 with different alkyl/arylisothiocyanates gave the corresponding thiosemicarbazide derivatives 9a-d, while their cyclo condensation reaction with ethyl chloro acetate gave the corresponding thiazolidin-4-one derivatives 10a-c. Moreover, condensation of 10a,c with aromatic aldehydes afforded the corresponding 5-arylidine-thiazolidin-4-one derivatives 11a,b. Cytotoxic evaluation of some of the newly synthesized compounds against human breast carcinoma cell line MCF-7 revealed that, these compounds showed promising activity compared with Doxorubicin as positive control.

Effect of substituents in the syntheses of phenyl-substituted dibenzonaphthyridines

A facile and elegant syntheses of linear and angular phenyl-substituted dibenzonaphthyridines from 2,4-dichloroquinolines through anilinoquinolines have been developed. The substituents in the 4th position of the anilinoquinoline and the temperature were found to play a vital role in the regulation of the yield towards the synthesis of the final compounds. The methyl group in the 7th position of the naphthyridin-11-ones was found to hinder the N-methylation reaction sterically, consequently increasing the reaction time than other derivatives.

Pharmacokinetics of 2-oxothiazolidine-4-carboxylate, a cysteine prodrug, and cysteine

The pharmacokinetics of both 2-oxothiazolidine-4-carboxylate (OTZ), a prodrug of cysteine, and total blood cysteine (cysteine plus cystine) were investigated in 18 healthy volunteers. OTZ was given either as a single, 2- hour intravenous infusion (56-66 mg/kg) or similarly infused (70-100 mg/kg) every 8 hours for four doses. Blood was assayed for OTZ, total blood cysteine, and glutathione. The pharmacokinetics of OTZ were analyzed alone and simultaneously with total cysteine using the NONMEM software package (University of California at San Francisco. The pharmacokinetics of OTZ were best described by Michaelis-Menten kinetics with parallel first-order elimination. OTZ was efficiently removed from the plasma. The Michaelis- Menten route of elimination was attributed to conversion of OTZ to total cysteine. At plasma OTZ concentrations equal to the Michaelis constant Km, 84% of OTZ was converted to total cysteine. These findings suggest that OTZ administered intravenously is an efficient means of increasing total blood cysteine.

Cancer diseases are widely recognised as an important medical problem and killing millions of people in a year. Chemotherapeutic drugs are successful against cancer in many cases and different compounds, including the analogues of natural substances, may be used for anticancer agents. Nucleoside analogues also have become a necessity for the treatment of cancer diseases. Nucleoside, nucleotide and base analogues have been utilised for decades for the treatment of viral pathogens, neoplasms and in anticancer chemotherapy. This review focuses on the different types of nucleosides and their potential role as anticancer agents. It also discusses the nucleoside analogues approved by FDA and in process of approval. The effect of the substitution on the nucleoside analogues and their pharmacological role is also discussed in the review. Owing to the advances in computational chemistry, it concludes with the future advancement and possible outcome of the nucleoside analogues.

Open source drug discovery: Highly potent antimalarial compounds derived from the tres cantos arylpyrroles

The development of new antimalarial compounds remains a pivotal part of the strategy for malaria elimination. Recent large-scale phenotypic screens have provided a wealth of potential starting points for hit-to-lead campaigns. One such public set is explored, employing an open source research mechanism in which all data and ideas were shared in real time, anyone was able to participate, and patents were not sought. One chemical subseries was found to exhibit oral activity but contained a labile ester that could not be replaced without loss of activity, and the original hit exhibited remarkable sensitivity to minor structural change. A second subseries displayed high potency, including activity within gametocyte and liver stage assays, but at the cost of low solubility. As an open source research project, unexplored avenues are clearly identified and may be explored further by the community; new findings may be cumulatively added to the present work.

Facile new industrial process for synthesis of teneligliptin through new intermediates and its optimization with control of impurities

Abstract: The present study is related to a commercially practicable new synthetic process for production of teneligliptin hydrobromide hydrate (1), a dipeptidyl peptidase-4 (DPP-4) inhibitor. Key strategies in the new process include preparation and isolation of new intermediates such as a better reactive nosyl derivative (3c) of l-proline methyl ester (2), its stereoselective substituted intermediate (5) with 1-(3-methyl-1-phenyl-1H-pyrazol-5-yl)piperazine (4) through SN2-type nucleophilic substitution, and isolation of carboxylic acid derivative 6 by deesterification of intermediate 5. The reaction conditions for preparation of new intermediates, and the additionally used coupling reaction for amidation and deprotection of N-Boc were optimized with control of impurities to improve the quality of drug molecule 1 with good yield. The developed synthetic strategy offers significant advantages over existing synthetic approaches, avoiding use of expensive reagents, long time consumption, and laborious procedures involving isolation of intermediates. The developed process for drug molecule 1, achieving overall yield of 37?39% over six sequential chemical transformations, enables rapid delivery of multi-kilogram quantities of the desired active pharmaceutical ingredient (API), meeting stringent purity requirements.
