O-methyltransferase CbzMT catalyzes iterative 3,4-dimethylations for carbazomycin biosynthesis.

Carbazomycins (-) are a subgroup of carbazole derivatives that contain oxygen at the C3 and C4 positions and an unusual asymmetric substitution pattern. Several of these compounds exhibit antifungal and antioxidant activities. To date, no systematic biosynthetic studies have been conducted on carbazomycins.

Genome Mining and Metabolic Profiling Reveal Cytotoxic Cyclodipeptides in var. Beijingensis.

Two new cyclodipeptide (CDP) derivatives () and another seven known cyclodipeptides () were isolated from 26D9-414 by the genome mining approach combined with genetic dereplication and the "one strain many compounds" (OSMAC) strategy. The structures of the new CDPs were established on the basis of 1D- and 2D-NMR and comparative electronic circular dichroism (ECD) spectra analysis. The biosynthetic gene clusters (BGCs) for these CDPs were identified through antiSMASH analysis.

Risk factors and prognostic nomogram for patients with second primary cancers after lung cancer using classical statistics and machine learning.

Previous studies have revealed an increased risk of secondary primary cancers (SPC) after lung cancer. The prognostic prediction models for SPC patients after lung cancer are particularly needed to guide screening. Therefore, we study retrospectively analyzed the Surveillance, Epidemiology, and End Results (SEER) database using classical statistics and machine learning to explore the risk factors and construct a novel overall survival (OS) prediction nomogram for patients with SPC after lung cancer.

Exploration in the mechanism of fucosterol for the treatment of non-small cell lung cancer based on network pharmacology and molecular docking.

Fucosterol, a sterol isolated from brown algae, has been demonstrated to have anti-cancer properties. However, the effects and underlying molecular mechanism of fucosterol on non-small cell lung cancer remain to be elucidated. In this study, the corresponding targets of fucosterol were obtained from PharmMapper, and NSCLC related targets were gathered from the GeneCards database, and the candidate targets of fucosterol-treated NSCLC were predicted.
