Paragraph 0023; 0032-0034, (2021/02/24)
The invention provides a retinoic acid derivative with multiple targets and a preparation method and application thereof A series of novel multi-target retinoic acid derivatives are designed and synthesized by taking a multi-target drug theory as guidance, taking Am580 as a parent nucleus and combining structural characteristics of Am580 to select N-hydroxyguanidine NO donors as NO sources, performing chemical modification on the NO donors to obtain a series of different donors, and coupling ester or amido bonds with the parent nucleus. Experiments prove that the derivative has the characteristics of higher activity, lower toxic and side effects and better anti-tumor effect. The structural general formula of the retinoic acid derivative with multiple target points is shown as the followingformula (I),.

A simple, cost-effective, environmentally benign, and efficient one-pot tandem approach to the synthesis of pharmaceutically important 1-aryl-1H-tetrazole-5-amines 3a-k and 4a-k has been described. The reaction utilized 1-phenyl thiourea, which was generated in situ from aqueous ammonia and isocyanates 1a-k, for the formation of heterocumenes using sodium azide, triethylamine, and ceric ammonium nitrate (CAN) to obtain various aryl-substituted 1H-tetrazole-5-amines (3a-k) in good to excellent yields.

Two series of compounds carrying 3-amino-1,2,4-triazole scaffold were synthesized and evaluated for their anticancer activity against a panel of cancer cell lines using XTT assay. The 1,2,4-triazole synthesis was revisited for the first series of pyridyl derivatives. The biological results revealed the efficiency of the 3-amino-1,2,4-triazole core that could not be replaced and a clear beneficial effect of a 3-bromophenylamino moiety in position 3 of the triazole for both series (compounds 2.6 and 4.6) on several cell lines tested. Moreover, our results point out an antiangiogenic activity of these compounds. Overall, the 5-aryl-3-phenylamino-1,2,4-triazole structure has promising dual anticancer activity.
