Paragraph 0008; 0089; 0094-0095, (2019/10/01)
The invention belongs to the field of medicinal chemistry, and relates to a preparation method and application of pongamol. The preparation method comprises the following steps: with 1,3-cyclohexanedione (6) as a starting raw material, carrying out a cyclization reaction to obtain 6,7-dihydro-4-(5H)-benzofuranone (7); carrying out acylation reaction on the compound (7) to obtain 5-acetyl-6,7-dihydro-4-(5H)-benzofuranone (8); carrying out dehydrogenation reaction on the compound (8) to obtain 1-(4-hydroxy-5-benzofuryl) ethyl ketone (3); carrying out methylation reaction on the compound (3) to obtain 1-(4-methoxy-5-benzofuryl) ethyl ketone (4); and condensing the compound (4) with benzoyl chloride to obtain the pongamol. According to the preparation method, the selected reagents are cheap and easy to obtain, the post-treatment method is simple, the reaction conditions are mild, and the product yield is high. Pharmacological activity experiments show that the synthesized compound has nerve injury resistance and anti-inflammatory activity, which means that the compound has a good application prospect in the field of treatment of nerve injury and inflammation related diseases.

Series of 4H-chromen-1,2,3,4-tetrahydropyrimidine-5-carboxylate derivatives 7a-7zb, 8a-8d and 9a-9d were synthesized and screened for their in vitro anti-mycobacterial activity against Mycobacterium tuberculosis H37Rv (MTB) and cytotoxicity against three human cancer cell lines including A549, SK-N-SH and HeLa. The results indicate that six compounds are more potent and 7za is most effective anti-mycobacterial derivative compared to the standard drugs Ethambutol and Ciprofloxacin. However, 12 compounds exhibited cytotoxicity against human neuroblastoma cell line; amongst them the compound 7v is most effective compared to the standard drug Doxorubicin. This is the first report assigning in vitro anti-mycobacterial, anticancer and structure-activity relationship for this new class of 4H-chromen-1,2,3,4-tetrahydropyrimidine-5- carboxylates.

A bioassay-guided fractionation and chemical examination of antihyperglycemic root extract of Derris indica resulted in isolation and characterization of two new furanoflavanoids (1, 2) along with thirteen known compounds (3-15). Their structures were determined on the basis of extensive spectroscopic (IR, MS, 1D and 2D NMR) data analysis and by comparison with the literature data. All the compounds were tested in vitro for intestinal α-glucosidase inhibitory and DPPH radical activity. New compounds (1, 2) displayed moderate intestinal α-glucosidase inhibitory as well as free radical scavenging activity. Other compounds also displayed varying degrees of moderate intestinal α-glucosidase inhibitory activity. Pongamol (6) displayed potent intestinal α-glucosidase inhibition.
