  一些黄烷酮衍生物的合成，生物学评估以及计算机代谢和毒性预测。

  摘要：

  黄酮化学上是花青素，以游离态或与单宁有关的糖苷（类黄酮）存在。类黄酮（黄酮的衍生物）具有多种药理活性，并且由于其具有黄嘌呤氧化酶抑制作用，因此还具有超氧化物清除活性。通过环化法从查耳酮合成了一系列的2-苯基-2,3-二氢色子-4-酮衍生物（黄酮衍生物），并评估了它们对某些革兰氏阳性和革兰氏阴性细菌的活性。IR，NMR和CHN分析证实了合成化合物的结构。抗菌研究的结果表明，化合物2b，2e，2f和2h具有对抗许多细菌菌株的活性。其中，化合物（2h）对所有菌株viz具有显着的活性。对金黄色葡萄球菌，S。sonnei，大肠杆菌，鼠伤寒沙门氏菌和霍乱弧菌的抑制浓度为25微克/毫升。化合物2f对大肠杆菌和鼠伤寒沙门氏菌的最低抑菌浓度为200微克/毫升，对S. sonnei，痢疾链球菌和霍乱弧菌的最小抑菌浓度为25微克/毫升。在计算机上对合成的化合物进行代谢和毒性研究，预测结果表明具有羟基官能团的化合

  Cytotoxic 2′,5′-dihydroxychalcones with unexpected antiangiogenic activity

  摘要：

  A series of 2',5'-dihydroxychalcones were synthesized and evaluated for cytotoxicity against tumor cell lines and human umbilical venous endothelial cells (HUVEC). It was found that chalcones with electron-withdrawing substituents on the B ring exhibited potent cytotoxicity against a variety of tumor cell lines while compounds with electron-releasing groups ere less potent in general. Those compounds with B ring replaced by extended or heteroaromatic rings exhibited significant bioactivity. Several compounds were shown to have marked cytotoxic selectivity towards HUVECs. Especially, among the synthesized compounds. 2-chloro-2'.5'dihydroxychalcone (2-3) showed the highest selectivity index up to 66 in comparison to HCT 116 cells. This Compound also exhibited strong inhibitory effects on the HUVEC tube formation in an in vitro model. When administered into BDF1 mice bearing Lewis lung carcinoma cells at 50 mg kg(-1) day (-1), 2-3 was found to inhibit the growth of tumor mass by 60.5%.

  Fifteen chalcones and three thiazolidinedione (TZD) chalcones were prepared to evaluate their peroxisome proliferator-activated receptor-γ (PPAR-γ) ligand-binding activities. Among the three TZDs, one compound possessed PPAR-γ transactivation potential, while the others showed antagonistic activity against PPAR-γ transactivation. Among the chalcones, compound 5 was the most potent, and structure–activity relationship studies indicated that a methoxyl group in position C-4 and hydroxyl group in position C-4′ or 5′ in chalcone plays a key role in determining the potency of PPAR-γ activation.

  研究人员制备了十五种查耳酮和三种噻唑烷二酮（TZD）查耳酮，以评估它们的过氧化物酶体增殖激活受体-γ（PPAR-γ）配体结合活性。在这三种 TZDs 中，一种化合物具有 PPAR-γ 转激活潜力，而其他化合物则对 PPAR-γ 转激活具有拮抗活性。结构-活性关系研究表明，查尔酮中 C-4 位的甲氧基和 C-4′ 或 5′ 位的羟基对 PPAR-γ 的激活效力起着关键作用。
