Fig. 14. Synthetic derivatives of CA-4 (1): These are produced by replacement, substitution, and modification at both the cis-olefinic bond and the aromatic rings of 1. N-acyl hydrazone CA-4 (4), azo CA-4 (3), 1, 3, 4, oxadiazole CA-4 (9), benzoxazole CA-4 (8) which are produced by replacement and modifications at the olefinic group. Through modifications to the cis-olefinic bond and aromatic rings of CA-4, analogs such as 2 and 7 (benzothiazole derivatives of CA-4 with fluorine), 5 and 6 (imidazole and indole derivatives of CA-4) are also synthesized.Published as part of Teka, Tekleab, Zhang, Lele, Ge, Xiaoyan, Li, Yanjie, Han, Lifeng & Yan, Xiaohui, 2022, Stilbenes: Source plants, chemistry, biosynthesis, pharmacology, application and problems related to their clinical Application-A comprehensive review, pp. 1-28 in Phytochemistry (113128) 197 on page 16, DOI: 10.1016/j.phytochem.2022.113128, http://zenodo.org/record/823464
