Synthesis, antiproliferative activity, and molecular docking studies of 4‐chlorothiocolchicine analogues
Bibliographic record
Abstract
Colchicine is a therapeutic agent currently used in therapies of many diseases. It also shows antimitotic effects, and its high cytotoxic activity against different cancer cell lines has been demonstrated many times. To overcome the limitations of colchicine use in anticancer therapy, we synthesized a series of novel triple-modified 4-chloro-7-carbamatethiocolchicines. All the synthesized compounds have been tested in vitro to evaluate their cytotoxicity toward A549, MCF-7, LoVo, LoVo/DX, and BALB/3T3 cell lines. Additionally, their mode of binding to β-tubulin was evaluated in silico. The majority of triple-modified colchicine derivatives exhibited significantly higher cytotoxicity than colchicine, doxorubicin, and cisplatin against tested cancerous cell lines with much higher selectivity index values for four of them.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
