were synthesized and evaluated against tumour and normal cell lines. Among these, the compound named 3j initially showed relevant cytotoxicity and selectivity for tumour cells. Three analogues of 3j were designed and synthesized keeping in view the structural requirements of this compound. Almost all the tested compounds displayed considerable cytotoxicity. However, 8a, one of the 3j analogues, was shown

series of 10 derivatives of 5-(5-amino-1,3,4-thiadiazole-2-yl)-3,4-dihydro-6-methyl-4-phenyl-pyrimidin-2(1H)-one and 10 derivatives of 3,4-dihydro-5-(5-mercapto-4H-1,2,4-triazol-3-yl)-6-methyl-4-phenyl pyrimidin-2(1H)-one have been synthesized. Among the synthesized derivatives, triazole substituted compounds have shown higher antibacterial inhibition when compared to the thiadiazole derivatives. All the

A new schiff base ytterbium complex was synthesized and used as catalyst for a three-component, one-potreactioninvolving 1,3-keto ester with urea or thiourea and aldehyde. The reactions resulted ...
In present research, we aim to afford the catalyst‐free, greener synthesis of diethyl 2,2′‐(1,2‐phenylenebis(methylene))bis(sulfanediyl)bis(6‐methyl‐4‐substitutedphenyl‐1,4‐dihydropyrimidine‐5‐carboxylate)derivatives via microwave irradiations. The reactions were also performed under conventional heating. The reaction times and yields thus obtained of the isolated desired products were compared too
