Abstract:
A mutasynthetic strategy is introduced for the mycosynthesis of naphthalene-based molecules (mutadalesols A-F) with directed substitution patterns and new frameworks by generating and using the ΔpksTL mutant strain of Daldinia eschscholzii. (±)-Mutadalesol A and its (+)-enantiomer are cytotoxic, and its (-)-enantiomer inhibits Toll-like receptor 5 (TLR5). The in-culture reactability of fungal oligoketide intermediates with 5-aminonaphthalen-1-ol (ANL) is demonstrated, shedding light on bioorthogonal accesses to unnatural molecule libraries valuable in drug discovery pipelines.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
