Tubuloclustin analogues with ether moiety: synthesis and evaluation of tubulin clustering and antimitotic activity in cancer cells
摘要:
New analogues of anticancer agent tubuloclustin N-[7(adamantan-l-yloxy)-7-heptanoyll-N-deacetylcolchicine with ether moiety in the linker between colchicine and adamantane fragments were synthesized from omega-(adamantan-l-yloxy)alkan-l-ols. These compounds effectively inhibited growth of human lung carcinoma cell line A549 (IC50 = 5-15.5 nM), induced both apoptosis and formation of tubulin clusters. The conjugates lacking ester carbonyl in the linker exhibit improved metabolic stability and are promising for further cytotoxicity studies in vivo.

A simple method for the synthesis of esters of tosyloxymethylphosphonic acid based on the adamantane series of alcohols and diethyl tosyloxymethyl phosphonate was developed. The di(adamantylalkyl) and di(adamantyloxyalkyl) tosyloxymethylphosphonates are of interest as key compounds in the synthesis of antiviral drugs of the nucleoside phosphonate class.
