  6-Alkylamino- and 2,3-Dihydro-3‘-methoxy-2-phenyl-4-quinazolinones and Related Compounds:  Their Synthesis, Cytotoxicity, and Inhibition of Tubulin Polymerization

  摘要：

  As part of our continuing search for potential anticancer candidates among 2-phenyl-4-quinolones and 2-phenyl-4-quinazolinones, two series of 6,7,2',3',4',5'-substituted 2-phenyl-4-quinazolinones and 6,2',3',4',5'-substituted 2,3-dihydro-2-phenyl-4-quinazolinones were synthesized and evaluated for cytotoxicity and as inhibitors of tubulin polymerization. In general, a good correlation was found between the two activities. Five of the 6-substituted heterocyclic 2-phenyl-4-quinozolinones (37-51) showed significant cytotoxicity against a panel of human tumor cell lines with EC50 values in the low micromolar to nanomolar concentration ranges. Compound 38 was the most potent of these compounds, as well as the most potent inhibitor of tubulin polymerization in this series. The activity of 38 was in the same range as those of the antimitotic natural products, colchicine, podophyllotoxin, and combretastatin A-4. Substituted 2-phenyl-4-quinazolinones and 2,3-dihydro-2-phenyl-4-quinazolinones also displayed highly selective cytotoxicity against the ovarian cancer 1A9 and P-gp resistant KB-VIN cell lines.

  non-amidine factor Xa inhibitor with good selectivity against thrombin and trypsin. A series of modifications of the three aromatic groups of 1 was investigated. Substitution of chlorine or bromine for fluorine on the aniline ring led to the discovery of subnanomolar factor Xa inhibitors. Positions on the anthranilic acid ring that can accommodate further substitution were also identified.

  The addition of mono- and dianions of ethyl N-pivaloyl-3-aminocrotonate to substituted nitroarenes, followed by action of silylating or acylating agent, leads to 3-aminoquinoline carboxylic acid derivatives. Hydrolysis and decarboxylation of the latter, carried out efficiently under relatively mild conditions, afford 3-aminoquinolines diversely substituted in the benzo-fused ring.

  Nitroaniline mustards have potential as hypoxia-selective cytotoxic agents, with reductive metabolism activating the nitrogen mustard by converting the electron-withdrawing nitro group to an electron-donating hydroxylamine or amine. However, the parent compounds have poor aqueous solubility, and their potencies are limited by low reduction potentials (E1/2 ca. -600 mV versus the normal hydrogen electrode)

  硝基苯胺芥子作为低氧选择性细胞毒剂具有潜力，其还原性代谢通过将吸电子硝基转化为供电子羟胺或胺来激活氮芥。然而，母体化合物的水溶性差，并且它们的效能受到低还原电位（相对于正常氢电极的E1 / 2约-600mV）和相应的缓慢的硝基还原速率的限制。为了解决这些局限性，制备了一系列通过吸电子羧酰胺基团连接的带有亲水性侧链的4-硝基苯胺芥菜，并评估了其对中国仓鼠细胞系的低氧选择性细胞毒性。N-[（N，N-二甲基氨基）乙基]羧酰胺衍生物具有优异的水溶性和改善的细胞毒性，但是它们的还原潜力虽然比非羧酰胺化合物高，但仍然很低，并且观察到的对缺氧细胞的选择性很小。还制备了一系列的2，4-二硝基苯胺芥末羧酰胺。这些化合物的还原电位在所需范围内（通过循环伏安法测得的E1 / 2约为-450 mV），并且对缺氧的毒性比需氧的UV4细胞高。选择性最高的化合物是5- [N，N-双（2-氯乙基）氨基] -2,4-二硝基苯甲酰胺（20，SN

  autoimmune diseases, and inhibition of RORγt with small molecules thus holds great potential as a therapeutic strategy. RORγt has a unique allosteric ligand binding site in the ligand binding domain, which is distinct from the canonical, orthosteric binding site. Allosteric modulation of RORγt shows high potential, but the targeted discovery of novel allosteric ligands is highly challenging via currently

  核受体RORγt是T辅助细胞17（Th17）细胞分化和增殖以及促炎性细胞因子（如IL-17a）产生的关键正调控因子。该途径的失调可导致各种自身免疫性疾病的发展，因此用小分子抑制RORγt具有作为治疗策略的巨大潜力。RORγt在配体结合结构域中具有独特的变构配体结合位点，其不同于典型的正构结合位点。RORγt的变构调节显示出很高的潜力，但是通过目前可用的方法，靶向发现新的变构配体具有很高的挑战性。在此，我们介绍RORγt的共价正构化学探针，该探针封闭正构，正构配体的结合，但仍允许变构配体结合。
