  • Patent number: 9994885
    Abstract: The present disclosure is directed to the biosynthetic pathway for a nonribosomal peptide synthetase (NRPS) derived drug and analogs thereof. The invention provides polynucleotide sequences useful for heterologous expression in a convenient microbial host for the synthesis of the NRPS-derived drug, the polypeptides encoded by such polynucleotides, expression vectors comprising the polynucleotides, host cells comprising the polynucleotides or expression vectors, and kits comprising a host cell. Also provided is a method for the production of ET-743, the NRPS-derived drug.

  • Patent number: 9650656
    Abstract: The biosynthesis of fungal bicyclo[2.2.2]diazaoctane indole alkaloids with a wide spectrum of biological activities have attracted increasing interest. Their intriguing mode of assembly has long been proposed to feature a non-ribosomal peptide synthetase, a presumed intramolecular Diels-Alderase, a variant number of prenyltransferases, and a series of oxidases responsible for the diverse tailoring modifications of their cyclodipeptide-based structural core. Until recently, the details of these biosynthetic pathways have remained largely unknown due to lack of information on the fungal derived biosynthetic gene clusters. Herein, we report a comparative analysis of four natural product metabolic systems of a select group of bicyclo[2.2.2]diazaoctane indole alkaloids including (+)/(?)-notoamide, paraherquamide and malbrancheamide, in which we propose an enzyme for each step in the biosynthetic pathway based on deep annotation and on-going biochemical studies.

  • Patent number: 9605015
    Abstract: The present invention relates to a novel polyene compound similar to nystatin, a method for preparing the same, and an antifungal drug comprising the novel polyene compound as an active ingredient. Compared to nystatin comprising one sugar, NNP, which is the polyene compound similar to nystatin, displays 300 times higher solubility and ten times lower cytotoxicity while maintaining antifungal activity, and thus can be useful in developing a novel polyene antifungal agent having improved solubility and less toxicity in terms of pharmacokinetics.
