Further insights on the secondary metabolites of a soft coral-derived fungus Aspergillus versicolor under guidance MS/MS-based molecular networking led to isolation seven known cycloheptapeptides, namely, asperversiamides A-C (1-3) and asperheptatides A-D (4-7) an unusual pyrroloindoline-containing new cycloheptapeptide, asperpyrroindotide A (8). The structure 8 was elucidated by comprehensive spectroscopic data analysis, its absolute configuration determined advanced Marfey's method. semisynthetic transformation 1 into successfully achieved reaction conditions were optimized. Additionally, series derivatives (10-19) asperversiamide (1) semi-synthesized their anti-tubercular activities evaluated against Mycobacterium tuberculosis H37Ra. preliminary structure-activity relationships revealed that serine hydroxy groups tryptophan residue are important activity.The online version contains supplementary material available at 10.1007/s42995-022-00157-8.

Cluster analysis chemical fingerprints and molecular scaffold 55 817 compounds microorganisms, macro-organisms showed that 76.7% isolated closely related microorganisms. Only 14.3% unique when macro-organism also considered. Studies targeting specific understudied microbial phyla result higher likelihood finding compounds, whereas depth geographic location collection little influence.
