The synthesis of some new 3-substituted quinazolin-4(3H)-ones and 3,4-dihydro-quinazolin-2(1H)-one derivatives and their biological evaluation as antitumor agents using the National Cancer Institute (NCI), disease oriented antitumor screening protocol are investigated. Compounds 2-[2-(4-chlorophenyl)-2-oxo-ethylthio]-3-(4-methoxyphenyl)quinazolin-4(3H)-one (3b), and 3-(4-chlorophenyl)-2-[2-(4-meth

angles (FOPA), that account for the directions of the nodes in the pi orbitals in the aromatic portion of those of the drugs in which the sulfonyl group was bound to a benzene ring. For thrombin inhibition, the size of the molecule was the dominant influence, while for trypsin inhibition the FOPA was the principal determinant of activity. The dependence of activity on the FOPA variables is perhaps the

reaction of 7 with CS2/KOH. Compound 3e was treated with o‐aminophenol or o‐aminothiophenol to give benzazoles 9a, 9b. N‐(Diaminomethylidene)‐4‐toluenesulfonamide (10) reacted with enaminones to yield pyrimidines 11, 12, 13, respectively. The structures of the compounds were elucidated by elemental and spectral analyses. Some selected compounds were screened for their in vitro antifungal activity. In general

approach for the synthesis of tailored‐design target sulfapyrimidine derivatives expected to show remarkable antimicrobialactivities. The approach is based on reacting arylsulfonyl guanidine with α,β‐unsaturated carbonyl compounds to afford N‐(4,6‐diarylpyrimidin‐2‐yl)arylsulfonamide or with ylidene derivatives to afford N‐(6‐aryl‐5‐cyanopyrimidin‐2‐yl)arylsulfonamide, N‐(4‐amino‐5‐cyano‐6‐(methylthi

predominant regulating factor in erythropoiesis. Herein we describe the identification of (4-hydroxy-2-(substitued sulfonamido)pyrimidine-5-carbonyl) glycine-based oral EPO secretagogues. Most of these compounds obviously increased the EPO level in Hep3B cells by stabilizing the hypoxia-inducible factor-α (HIF-α). Furthermore, their potential inhibitory activities against HIF prolylhydroxylase domain (PHD)
