Abstract

fetched live from OpenAlex

Cowabenzophenone A was isolated from an endophytic fungus Aspergillus terreus isolated from a mangrove plant Bruguiera gymnorrhyza. The structure was determined by analysis of 1D and 2D NMR spectra and mass spectrometric data as a tetracyclo[7.3.3.33,11.03,7]tetradecane-2,12,14-trione skeleton. When the compound was tested in vitro for its ability to inhibit inflammations, α-glucosidase inhibitory activities and its antimicrobial properties, it showed an anti-inflammatory activity amounting to an IC50 of 12.1 µg/mL, α-glucosidase inhibitory activity, with IC50 values of 7.8 ± 0.5 μM, and antibacterial activity against Bacillus subtilis TISTR 088, and Bacillus cereus TISTR 688 with MIC values of 1 μg/mL and 2 μg/mL respectively. The compound showed cytotoxicity against HCT 116 colon cancer cell line with an IC50 value of 10.1 ?M, and also showed a considerably high potential towards anti-filarial activities by resulting MIC, IC50 and LC50 values of 0.358 ± 0.02 mg/mL, 0.708 ± 0.021 mg/mL and 3.89 ± 0.18 mg/mL, respectively, in comparison to the standard drug Ivermectin (IVM).

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
