An efficient green synthesis of some new 4H-pyrimido[2,1,b]benzimiazoles and 4H-pyrimido[2,1,b]benzothiazoles promoted by guanidinium chloride
A facile and highly efficient protocol was applied successfully to synthesize 4H-pyrimido[2,1,b]benzimiazoles and 4H-pyrimido[2,1,b]benzothiazoles through one-pot three-component cyclocondensation reactions of 2-aminobenzimidazole or 2-aminobenzothiazole with dimedone and aromatic aldehydes in the presence of guanidinium chloride under solvent-free conditions. The reactions us...

متن کاملSynthesis, biological and pharmacological activities of 2-methyl-4H- pyrimido[2,1-b][1,3]benzothiazoles
Anilines 1a-h on reaction with potassium thiocyanate and bromine in acetic acid yielded substituted 2-amino[2,1-b][1,3]benzothiazoles 3a-h. The compounds 3a-h on reaction with ethyl acetoacetate and pheylidine acetoacetate, yielded, 2-methyl-4-H-pyrimido[2,1b][1,3]benzothiazole-4-ones 4a-h and ethyl 4-phenyl-2-methyl-4H–pyrimido[2,1b][1,3]benzothiazole-3-carboxylates 5a-h respectively. Pheylidi...
متن کاملMicrowave Assisted Synthesis, Pharmacological Activities, and Molecular Docking Studies of Ethyl 2-[2-substituted-4-(thiophenyl)thiazolyl] acetates
A series of ethyl 2-[2-arylamino-4-(thiophen-2-yl)thiazol-5-yl] acetates (5a-5k) and ethyl 2-[2-(arylhydrazino)-4-(thiophen-2-yl)thiazol-5-yl] acetates (9a-9g) were synthesized and screened for their anti-inflammatory, analgesic, and antioxidant activities. In vivo test results showed that the compounds with halogen substitution (5c, 5g, 5h, 5i and 5j) at the para position on the 2-aryl amino g...
متن کاملEGFR tyrosine kinase targeted compounds: in vitro antitumor activity and molecular modeling studies of new benzothiazole and pyrimido[2,1-b]benzothiazole derivatives
In this study, we illustrate computer aided drug design of new benzothiazole and pyrimido[2,1-b]benzothiazole derivatives as epidermal growth factor receptor tyrosine kinase (EGFR-TK) inhibitors. Compounds 1-5 were screened at NCI, USA, for antitumor activity against non-small cell lung cancer (NCI-H522), colon cancer (HCT-116, HCT-15 and HT29) and breast cancer (MDA-MB-468 and MDA-MB-231/ATCC)...
