New series of sulfonamide derivatives of [1,3,4]thiadiazolo[3,2-a]pyrimidine were synthesized and investigated as antitumor agents. Some of the newly prepared compounds were tested for their in vitro and in vivo antitumor activities. Preliminary biological studies revealed that compounds 4c, 4f, and 4j exhibited the highest affinity to DNA, while compounds 4h,i, 6a–c, 8 and 12–14 exhibited moderate
合成了[1,3,4]噻二唑并[3,2- a ]嘧啶的新系列磺酰胺衍生物,并将其作为抗肿瘤剂进行了研究。测试了一些新制备的化合物的体外和体内抗肿瘤活性。初步生物研究显示,化合物4C,4F,和4J表现出对DNA的最高的亲和力,而化合物4h中,我,6A - Ç,8和12 - 14表现出中等的活性。另外,化合物4j,4f和4c结果显示,与5-氟尿嘧啶相比,接种Ehrlich腹水细胞的小鼠的寿命增长百分比最高(阳性对照)。报告了详细的合成,光谱和生物学数据。
Discovery of [1,2,4]triazolo[4,3-<i>a</i>]pyrazine derivatives bearing a 4-oxo-pyridazinone moiety as potential c-Met kinase inhibitors
We disclosed the preparation and biological evaluation of a series of [1,2,4]triazolo[4,3-a]pyrazine derivatives bearing 4-oxo-pyridazinone moieties, which demonstrated potent inhibition of c-Met kinase, culminating in the discovery of 22i.

5-Hydroxy-7-methyl-3H-thiazolo [4,5-b]pyridin-2-one was obtained by the reaction of 4-iminothiazolidin-2-one with acetoacetic ester. Further structural modifications include the introduction of diversity at the C-5 and C-6 positions. The anti-inflammatory action of novel thiazolo[4,5-b]pyridine-2-one derivatives was evaluated in vivo employing the carrageenan-induced rat paw edema method. The antioxidant activity of the synthesized compounds was evaluated in vitro by the method of scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals.
