New sorbicillinoid derivatives with GLP-1R and eEF2K affinities from a sponge-derived fungus Penicillium chrysogenum 581F1

Two new sorbicillinoids, 13-hydroxy-dihydrotrichodermolide (1) and 10,11,27,28-tetrahydrotrisorbicillinone C (2), were isolated from the sponge-derived fungus Penicillium chrysogenum 581F1. Their structures were determined on the basis of spectroscopic analysis. Compounds 1 and 2 displayed high affinities to target proteins GLP-1R (diabetes) and eEF2K (cancer) with K_d values of 0.0285 μM, 0.0162 μM for GLP-1R and 0.118 μM, 0.0746 μM for eEF2K, respectively.
