Triaminotriazine DNA helicase inhibitors with antibacterial activity
摘要:
Screening of a chemical library in a DNA helicase assay involving the Pseudomonas aeruginosa DnaB helicase provided a triaminotriazine inhibitor with good antibacterial activity but associated cytotoxicity toward mammalian cells. Synthesis of analogs provided a few inhibitors that retained antibacterial activity and demonstrated a significant reduction in cytotoxicity. The impact of serum and initial investigations toward a mode of action highlight several features of this class of compounds as antibacterials. (C) 2005 Elsevier Ltd. All rights reserved.
Discovery of novel 1,3,5-triazine-thiazolidine-2,4-diones as dipeptidyl peptidase-4 inhibitors with antibacterial activity targeting the S1 pocket for the treatment of type 2 diabetes
An efficient and general one-pot reaction to a novel series of hybrid thiazolidine-4-one-1,3,5-triazine derivatives was developed. The easy work-up of the products, rapid reaction, and mild conditions are notable features of this protocol. These molecules were found to exhibit potent activity against a panel of Gram-positive and Gram-negative micro-organisms.

Condensation of 5-cyano-2-hydrazino-3-N-methyl-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin-4-one (3a and 3b) with 2 4-bisalkyl/arylamino-6-chloro-s-triazine (4) gave the corresponding 2,4-bisalkyl/arylamino-6-[5'-cyano-3'-N-methyl]-6'-phenyl/p-chlorophenyl-3',4'-dihydropyrimidin-4'-one-2'-yl-hydrazino-s-triazines (5a-n and 6a-n). The compounds 4 have been prepared by the condensation of cyanuric chloride and different alkyl/aryl amines. The reaction between 5-cyano-3-N-methyl-2-methylthio-6-phenyl/p-chlorophenyl-3,4-dihydropyrimidin-4-one (2a and 2b) with hydrazine hydrate furnished 3a and 3b, respectively. The condensation of 6-phenyl/p-chlorophenyl/5-cyano-2-mercapto-3,4-dihydropyrimidin-4-one (1a and 1b) with methyl iodide yielded 2a and 2b, respectively. All the products have been evaluated in vitro for their antimicrobial activity against several microbes and antitubercular activity against Mycobacterium tuberculosis H37 Rv.
