4-Formylcolchicine (compound 7) exhibits antiproliferative action against A549, HT-29, and HCT116 cells, with IC50s of 1.007, 0.128, and 0.054 µM, respectively[1].

| ln Vivo |
Liver fibrosis was induced by chronically (7 weeks) administering CCl4, to rats. Animals were divided into four groups: (a) controls, (b) treated with CCI, alone, (c) treated with CCl4 and colchicine and (d) treated with CCl4 and 4-Formylcolchicine bound to lactosaminated serum albumin (FC-LASA). Liver dysfunction was monitored by biochemical tests (alkaline phosphatase [ALP], γ-glutamyltransferase [γGT], aspartate and alanine transaminases [AST and ALT], albumin and total bilirubin). Fibrosis was evaluated by determining hydroxyproline and by microscopic examination. The exposure to CCl4 produced major alterations of liver structure and collagen deposition. These effects were partially counteracted by colchicine and to a greater extent by FC-LASA. Morphological findings paralleled biochemical data. The information reported here indicates that colchicine has an antifibrotic activity on the liver of intoxicated rats and that FC-LASA is more active than colchicine itself as an antifibrotic agent [1].

Effect of colchicine and its derivatives on liver fibrosis [1]
To study the effects of colchicine derivatives on liver fibrosis in vivo, we used adult Sprague-Dawley male rats (about 250 g body wt.). The animals were divided into four groups. (A) Controls received 2 ml.kg-1 body wt. mineral oil by intraperitoneal route and 250 ~tl of saline by injection into the tail vein three times a week for 7 weeks; (B) Animals were intoxicated with carbon tetrachloride. They were treated as those of groups A, except that they received a mixture of mineral oil and carbon tetrachloride (65:35 v/v, 2 ml'kg-1 body wt.); (C) The animals belonging to this group were treated as those of group B but they received colchicine (120 ~tg-kg-1 body wt., dissolved in saline) instead of saline; and (D) animals were treated as in (C), but colchicine was replaced by FC-LASA (120 ~tg.kg-~ body wt., as free colchicine). Doses were adjusted to body wt. and expressed as free colchicine. Owing to the high toxicity of CC14 (only about 40-50% of the animals survived 7 weeks' treatment), we began the experiment with 50 animals (various treatments) and 15 animals (controls), to have the final number of animals reported in Table 1. At the end of the experiment, animals were anaesthetised with diethyl ether and their blood was drained by heart puncture and collected in pre-heparinated vessels. Plasma was prepared by centrifugation at 1000 x g for 10 min and some biochemical parameters (alkaline phosphatase (ALP), aspartate and alanine transaminases (AST and ALT) y-glutamyl transferase (yGT), albumin and total bilirubin) were determined by commercial kits. Livers were used to verify collagen content (as hydroxyproline) and for histological examination. |

| Additional Infomation |
Histological findings agree with the biochemical tests and especially with the determination of liver hydroxyproline, which assesses liver fibrosis better than microscopic evaluation. All tests indicate that FC-LASA is more effective than colchicine to decrease liver fibrosis following CC14 administration in the rat. [1]
Novel colchicine derivatives possessing various substituents at the C4 position were prepared. Among them, 4-halo derivatives 3-6 were found to exhibit higher activity against cancer cell lines (A549, HT29, HCT116) as well as on mice transplanted with the HCT116 human colorectal carcinoma cell line than colchicine (1). Further, utilizing the 4-substituted colchicines, we prepared pro-drugs having a dipeptide side chain and demonstrated that these pro-drugs were activated by cathepsin B, an enzyme overexpressed in tumor cells, and exhibited selective toxicity to the tumor cells.[2] |
