A synthetic method for 7-hydroxy-5-methoxyisoflavones starting from 5,7-dihydroxyisoflavones was developed. Dimethylcarbamoylchloride was proposed for protection of the 7-hydroxy group. Aminomethylation of the synthesized 7-hydroxy-5-methoxyisoflavones by formaldehyde aminals was studied.

The base‐catalyzed chromone ring‐closure reaction was developed for one‐step synthesis of various 2‐(ω‐carboxyalkyl)isoflavones bearing electron‐donating and electron‐withdrawing groups.
Structure-activity relationship study of 4′-O-methylgrynullarin derivatives for the development of novel anticancer agents based on anti-austerity strategy
that its derivatives might have the potential to lead to novel anti-cancer agents based on anti-austerity strategy. The divergent synthesis of 4′-O-methylgrynullarin derivatives using the Suzuki-Miyaura coupling reaction as a key step and the evaluation of the synthesized derivatives revealed a clear structure-activityrelationship. We found that the 6-prenyl moiety and 7-phenolic hydroxy group on the
4'- O -Methylgrynullarin 1及其衍生物2-4在营养缺乏条件下表现出优先的细胞毒性,而在正常营养条件下没有细胞毒性,表明其衍生物可能具有产生基于抗紧缩性的新型抗癌剂的潜力战略。以 Suzuki-Miyaura 偶联反应为关键步骤的 4'- O -methylgrynullarin 衍生物的不同合成和对合成衍生物的评估揭示了明确的构效关系。我们发现异黄酮骨架上的 6-异戊二烯基部分和 7-酚羟基对于优先细胞毒性是必不可少的,即使C上的取代基-环比1-4更简单,一定程度上保持了细胞毒性。

and decay cure. UV analysis and optical band was also calculated. Computational analysis were carried out and optical band and Judd-Ofelt intensity parameters were determined. Furthermore, the pharmacological activities such as antimicrobial and antioxidant activity of ligand CHDME and its analogous Europium complexes were also examined. The methods used were tube dilution method for calculating antimicrobial
Structure–Activity Relationship Prediction‐Based Synthesis and Cytotoxicity Evaluation against the HEp‐2 Laryngeal Carcinoma Cell of Isoflavone–Cytisine Mannich Bases
web platform. The validation of the models using an external test set proved that the models can be used to predict the activity of newly designed compounds such as 8-cytisinylmethyl derivatives of 5,7- and 6,7-dihydroxyisoflavones. The synthetic procedure for selective aminomethylation of 5,7-dihydroxyisoflavones with cytisine was developed. In vitro testing identified compound 7 f with cisplatin-level
