Multimethod-guided discovery of novel α-pyrone dimers with cardiomyocyte-protective activity against cold ischemia injury from the coral-derived Talaromyces sp. TJ403-AL05.
Guided by molecular networking, HSQC-based DeepSAT, and SMART analyses, a chemical investigation of the coral-derived fungus Talaromyces sp. TJ403-AL05 led to the isolation and identification of taladipyrones A-I (1-9), a series of new α-pyrone dimers with four distinct skeletons. Among these, compounds 1 and 9 represe...
