Investigating the anticancer properties of six benzothiazolopyrimidine derivatives on colon carcinoma cells, in vitro and in vivo
Bibliographic record
Abstract
Abstract Colorectal cancer (CRC) is the third most common cancer in the world. Despite considerable improvements in the treatment of this cancer, further research to discover novel and more effective agents is ongoing. In this study, possible cytotoxic and apoptotic properties of six benzothiazolopyrimidine derivatives were studied. To assess the IC 50 values of these agents, MTT assay was performed on HCT 116, CT26, and NIH/3T3 cells. Moreover, cell death mechanism induced by studied compounds was evaluated by PI/annexin V staining. Then, based on molecular docking results and in vitro experiments, the compounds with the highest anticancer properties were further analyzed in vivo in a mouse model of CRC. MTT results indicated that BTP(1) and BTP(4) had the highest selective cytotoxicity on colorectal cancer cells. Furthermore, flow cytometry results demonstrated a considerable increase in the percentage of the early apoptotic cells in BTP(1)‐ and BTP(4)‐treated groups. In vivo studies confirmed the antitumor properties of the two compounds by a significant regression in tumor size of BTP(1)‐ and BTP(4)‐treated mice compared to control groups. Histopathological examination of tumor tissues showed an increased number of apoptotic cells in these two groups compared to the control animals. Additionally, hematoxylin and eosin staining of the spleen and liver of treated mice did not exhibit considerable tissue damage. Thus, BTP(1) and BTP(4) can be considered promising agents in the treatment of colorectal cancer, although further experiments are required to assess their mechanism of action before their application in clinical studies.

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.
