Paragraph 0004; 0007; 0010; 0017-0020, (2020/07/12)
The invention discloses a preparation method of adapalene. According to the preparation method of adapalene, 2-methoxycarbonyl-6-naphthol p-toluenesulfonate and 4-methoxyphenylboronic acid which are low in price and easy to obtain are used as raw materials and bis (triphenylphosphine) nickel chloride is used as a catalyst, Suzuki coupling is performed to obtain 6-(4-methoxyphenyl)-2-methyl naphthoate, then alkylation reaction with 1-adamantanol is made to obtain 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-methyl naphthoate, and finally ester hydrolysis is performed to obtain the target product adapalene. The method is simple in process, raw materials are available, the yield is high and the cost is low, and the quality can reach a satisfactory level.

To investigate the influence of the adamantyl group on the biological properties of known HDAC inhibitors with a 4-phenylcinnamic skeleton, a series of compounds having the adamantyl moiety in the cap structure were synthesized and compared to the corresponding hydroxamic acids lacking this group. An unexpected finding was the substantial reduction of inhibitory activity toward the tested enzymes, in particular HDAC6, following the introduction of the adamantyl group. In spite of the reduced ability to function as HDAC inhibitors, the compounds containing the adamantyl moiety still retained a good efficacy as antiproliferative and proapoptotic agents. A selected compound (2c; ST3056) of this series exhibited an appreciable antitumor activity against the colon carcinoma xenograft HCT116.
