The interaction of tubulin with thiocolchicine and two thiocolchicine analogues, one lacking the B ring and one with a six-membered B ring, has been studied by using near-UV and CD spectroscopies. Rapid, reversible binding of the latter analogue to tubulin

Three series of novel thiocolchicine analogs, N-acyl-, N-aroyl-, and N-(substituted benzyl)-deacetylthiocolchicinoids, have been synthesized and evaluated for their cytotoxicity against various tumor cell lines, especially solid tumor cell lines, and for their inhibitory effects on tubulin polymerization in vitro.

Several B-ring variations of O-methyl androbiphenyline (8), newly accessible from (-)-(M,7S)-colchicine via photooxygenation and subsequent endoperoxide-transformation, were synthesized and evaluated for their inhibitory effects on tubulin assembly in vitro. The amino-allocolchicinoid (9), a key compound in this study, was transformed

Biochemical and biophysical research communications, 161(2), 544-550 (1989-06-15)
Thiocolchicine, a colchicine analog in which the C-10 methoxy is replaced with a thiomethyl moiety, was shown to bind with high affinity to the colchicine site on tubulin (Ka = 1.07 +/- 0.14 x 10(6) M-1 at 23 degrees C).
