F. published an article.Category: amides-buliding-blocks The title of the article was Synthesis and antimicrobial evaluation of new series of quinazolin-5-one derivatives. And the article contained the following:

A new series of quinazolinone derivatives, e.g., I, were synthesized starting with anthranilic acid and cinnamoylisothiocyanate in high yields 55-99%. The study of the biol. activity of all the novel compounds is reported. The minimal inhibitory concentration of some quinazolin-5-one derivatives, e.g., I, showed potential activity against both Gram (+ve) and Gram (-ve) microorganisms more than the reference cefotaxime. In addition, some derivatives of quinazolin-5-one, e.g., I, can be considered as antifungal agents comparing with the standard drug nystatin. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Category: amides-buliding-blocks

A. K., Ajeesh Kumar; Bodke, Yadav D.; Gowda, Ashwath N.; Sambasivam, Ganesh; Bhat, Kishore G. published an article in 2017, the title of the article was Design, Synthesis, and Evaluation of the Anticancer Properties of a Novel Series of Imidazolone Fused Pyrazolo[1,5-a]pyrimidine Derivatives.Name: 2-(4-Methylbenzamido)acetic acid And the article contains the following content:

A novel series of imidazolone fused pyrazolo[1,5-a]pyrimidine derivatives has been designed and synthesized using a convergent approach, and the structures of these compounds were confirmed by 1H NMR, 13C NMR, ESI-MS, and IR analyses. These new compounds were tested for their in vitro antiproliferative activity using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Out of the 20 derivatives prepared in the current study, some compounds exhibited good anticancer activities tested against HeLa cells and HepG2 cells. However, the in vitro anticancer activity of compound I against HeLa, HepG2, and MCF-7 cell lines is superior to the marketed drugs Paclitaxel and SAHA.
