BPKS from Botrytis cinerea is a novel type III polyketide synthase that accepts C4–C18 aliphatic acyl-CoAs and benzoyl-CoA as the starters to form pyrones, resorcylic acids and resorcinols through sequential condensation with malonyl-CoA. The catalytic efficiency (kcat/Km) of BPKS was 2.8 × 105 s−1 M−1 for palmitoyl-CoA, the highest ever reported. Substrate docking analyses addressed the unique features of BPKS such as its high activity and high specificity toward long chain acyl-CoAs.
Disclosed are novel heterocyclic derivatives, useful for the treatment of various disease states, in particular cardiovascular diseases such as atrial and ventricular arrhythmias, intermittent claudication, Prinzmetal's (variant) angina, stable and unstable angina, exercise induced angina, congestive heart disease, and myocardial infarction. The compounds are also useful in the treatment of diabetes, and for increasing HDL plasma levels in mammals.
Lipidic polyketides: We examined the in vitro reactions catalyzed by RpsA, a bacterial typeIIIpolyketidesynthase (PKS) from Rhodospirillum centenum. RpsA is the first typeIII PKS shown to be able to efficiently accept two molecules of extender methylmalonyl‐CoA and to synthesize tetraketide compounds through aldol condensation induced by methine proton abstraction.
