Spirocyclic nonpeptide glycoprotein IIb–IIIa antagonists. Part 3: synthesis and SAR of potent and specific 2,8-diazaspiro[4.5]decanes
摘要:
The synthesis and biological activity of analogues containing spiro piperidinylpyridine and pyrrolidinylpyridine templates are described. The potent activity of these compounds as platelet aggregation inhibitors demonstrates the utility of the spiro structures as central template for nonpeptide RGD mimics.

alkoxy group (R) of the phenyl ring, the sulfonamide type (X), and the length of the methylene chain linking the carboxylic acid, and the results were discussed in detail. From this study, we have clearly demonstrated that introduction of a carboxylic acid group to the 5'-sulfonamide moiety of the phenyl ring greatly enhanced PDE5 inhibitory activity, probably by mimicking the phosphate group of cGMP

(E)-4[3'-(1-Adamantyl)-4'-hydroxyphenyl]-3-chlorocinnamic acid (3-Cl-AHPC) induces the cell cycle arrest and apoptosis of cancer cells. Because its pharmacologic properties solubility, bioavailability, and toxicity required improvement for translation, structural modifications were made by introducing nitrogen atoms into the cinnamyl ring and replacing its E-double bond with XCH2 (X = O, N, and S) with the objective of enhancing these properties without impacting apoptosis-inducing activity. Analogues having nitrogen atoms in heterocyclic rings corresponding to the cinnamyl phenyl ring displayed equal or higher biological activities. The pyrimidine and pyridine analogues were more soluble in both phosphate-buffered saline and water. While the 2,5-disubstituted pyridine analogue was the most potent inducer of KG-1 acute myeloid leukemia cell apoptosis, on the basis of apoptotic activity in KG-1 cells and solubility, the 2,5-disubstituted pyrimidine proved to be the more promising candidate for treatment of acute myeloid leukemia.
(E)-4([3'-亚胺基-4'-羟基苯基])3-氯丙烯酸包围苯环诱导癌细胞周期阻滞和凋亡。为了改进其药理活性,如溶解度、生物利用度和毒性,引入了氮原子到苯环的羟基取代位点,并将双键改 became XCH2(X = O,N,S),以提高药理活性/毒性。具有含N原子的杂环对应于表间环部分的类药物显示了相等或更高的生物活性。而含有嘌呤的对位的二甲苯碱和二甲基并环二甲苯碱相当容易在磷酸缓冲盐和水这些易溶溶剂中暴漏。其中,二甲苯并二取代的苯碱类药物是最有效诱导粒流感-1(KG-1)急性髓系白血病细胞凋亡的药物。基于对粒流感-1细胞的凋亡作用和社会性,二苯基苯碱似乎在急性髓系白血病治疗方面是一个更为有前途的候选药物。
