钯催化邻乙酰基苯甲酸的合成:2-羟基-3-苯基-1,4-萘醌和吲哚[2,3 - b ]萘-6,11-二酮的新有效途径
摘要:
我们在这里描述了一种新的,高效的,一般的合成方法,该方法通过Heck钯催化的正丁基乙烯基醚与邻溴代苯甲酸酯的芳基化反应来合成邻乙酰基苯甲酸,并将这些化合物用作合成3-苄叉基异色满1的原料,4-二酮,其容易重排为2-羟基-3-苯基-1,4-萘醌。还描述了该策略在吲哚[2,3 - b ]萘-6,11-二酮合成中的应用。
ring within pocket A of the enzyme. On this basis, chemical modifications were proposed to increase inhibition activity. Synthetic routes had to be adapted and optimized to yield the desired substituted 4- and 5-arylthiazolinethiones. Their biological evaluation shows that 5-aryl regioisomers are systematically less potent than the corresponding 4-aryl analogs. Substitution on the phenyl ring does not

aromaticity criterion to evaluate the antifungal activity of two series of indol-4-ones. A linear regression analysis of NICS and antifungal activity showed that both tested variables were significantly related (p < 0.05); when aromaticity increased, the antifungal activity decreased for series I and increased for series II. To verify the validity of the obtained equations, a new set of 44 benzofuran-4-ones

Embodiments of small molecule inhibitors of hypoxia inducible factor 1 (HIF-1) and pharmaceutical compositions thereof are disclosed. The disclosed compounds suppress HIF-1 activity by inhibiting the interaction between the HIF- 1 α subunit and transcriptional co-activator protein p300. Embodiments of methods for making and using the small molecule inhibitors are also disclosed.
