New thiocolchicine derivatives (1-8) were designed as less toxic anticancer agents possessing the power full anticancer activity of colchicine. The synthesis and biological evaluation of these compounds were described. As a preliminary result of biological in vitro investigation, compounds 1, 6, and 7 showed lower toxicities than that of colchicine in combination with potent anticancer activities.

A series of 22 amine analogs of thiocolchicine were synthesized using the reductive amination reaction. The antiproliferative activities of these compounds were tested against four tumor cell lines as well as one normal cell line. The tested analogs exhibited IC values in the nanomolar range accompanied by high selectivity indexes, and most importantly, they were able to break the drug resistance of the human colon adenocarcinoma resistant cell line (LoVo/DX).

Colchicine is a plant alkaloid with a broad spectrum of biological and pharmacological properties. It has found application as an anti-inflammatory agent and also shows anticancer effects through its ability to destabilize microtubules by preventing tubulin dimers from polymerizing leading to mitotic death. However, adverse side effects have so far restricted its use in cancer therapy.

The cardinal role of microtubules in cell mitosis makes them interesting drug targets for many pharmacological treatments, including those against cancer. Moreover, different expression patterns between cell types for several tubulin isotypes represent a great opportunity to improve the selectivity and specificity of the employed drugs and to design novel compounds with higher activity only on cells of interest. In this context, tubulin isotype βIII represents an excellent target for anti-tumoral therapies since it is overexpressed in most cancer cells and correlated with drug resistance.

Colchicine, a pseudoalkaloid isolated from , has been identified as a potent anticancer agent because of its strong antimitotic activity. It was shown that colchicine modifications by regioselective demethylation affected its biological properties. For demethylated colchicine analogs, 10-demethylcolchicine (colchiceine, ) and 1-demethylthiocolchicine (), a series of 12 colchicine derivatives including 5 novel esters (- and -) and 4 carbonates (- and -) were synthesized.

Colchicine (COL) shows strong anticancer activity but due to its toxicity towards normal cells its wider application is limited. To address this issue, a library of 17 novel COL derivatives, namely N-carbamates of N-deacetyl-4-(bromo/chloro/iodo)thiocolchicine, has been tested against two types of primary cancer cells. These included acute lymphoblastic leukemia (ALL) and human breast cancer (BC) derived from two different tumor subtypes, ER+ invasive ductal carcinoma grade III (IDCG3) and metastatic carcinoma (MC).
