Synthesis, structure elucidation, DNA-PK, PI3K, anti-platelet and anti-bacteria activity of linear 5, 6, and 10-substituted-2-morpholino-chromen-oxazine-dione and angular 3, 4, 6-substituted-8-morpholino-chromen-oxazine-2,10-dione

Coumarin, a naturally occurring or synthesised phytochemical, displays a wide range of biological activities. However, chromen-2-ones fused with 1,3-benzoxazine rings is not well documented and there is a gap in the literature which required engaging. The substituted-2-thioxo-chromen-oxazine linear compounds 14a-i and angular compounds 16a-e were synthesised from the reaction of hydroxy-substitute
天然存在或合成的植物化学香豆素具有广泛的生物活性。然而,与1,3-苯并恶嗪环稠合的2-亚甲基色酮没有得到充分的证明,并且在文献中存在空白,需要进行接合。取代的-2-硫代-色烯-恶嗪线性化合物14a-i和角化合物16a-e是由羟基取代的亚甲基-羧酸10-13与新鲜制备的Ph3P(SCN)2的反应合成的。由相应的恶嗪14和16与吗啉反应,合成了2-Morpholino-取代的chromen-oxazine-4,8-dione和8-morpholino-取代的chromen-oxazine-2,10-dione 15a-f和17。 。对于羟基取代的亚甲基-羧酸观察到PI3K活性,其化合物13b显示出中等的PI3Kγ(IC50 =5.56μM)和PI3Kα(IC50 =14.7μM)活性。另外,8-吗啉代-色烯-恶嗪-2,10-二酮17a显示同工型选择性PI3Kδ活性,IC50 = 5.08μ
