Quantification of N-acetylcysteamine activated methylmalonate incorporation into polyketide biosynthesis

open access: yesBeilstein Journal of Organic Chemistry, 2013
Polyketides are biosynthesized through consecutive decarboxylative Claisen condensations between a carboxylic acid and differently substituted malonic acid thioesters, both tethered to the giant polyketide synthase enzymes.

Exploitation of Aspergillus terreus for the Production of Natural Statins

open access: yesJournal of Fungi, 2016
The fungus Aspergillus (A.) terreus has dominated the biological production of the “blockbuster” drugs known as statins. The statins are a class of drugs that inhibit HMG-CoA reductase and lead to lower cholesterol production.

Bioinspired iterative synthesis of polyketides [PDF]

open access: yesFrontiers in Chemistry, 2015
Diverse array of biopolymers and second metabolites (particularly polyketide natural products) has been manufactured in nature through an enzymatic iterative assembly of simple building blocks. Inspired by this strategy, molecules with inherent modularity can be efficiently synthesized by repeated succession of similar reaction sequences.

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

open access: yesBiological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Free Phenolic Hydroxyl Groups Govern the Anticancer Activity of α‐Mangostin: A Structure–Activity Relationship Insight

open access: yesChemFoodChem, EarlyView.
Free phenolic hydroxyl groups in the chemical structure of the natural xanthone α‐mangostin (MGT) contribute positively to achieving the anticancer profile against murine colon cancer, murine triple negative breast cancer, and human osteosarcoma cancer. ABSTRACT The α‐mangostin (MGT) is a natural xanthone obtained from the pericarp of mangosteen fruit (

Identification of a Polyketide Synthase Gene Responsible for Ascochitine Biosynthesis in Ascochyta fabae and Its Abrogation in Sister Taxa

open access: yesmSphere, 2019
The polyketide-derived secondary metabolite ascochitine is produced by species in the Didymellaceae family, including but not restricted to Ascochyta species pathogens of cool-season food legumes.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

open access: yesChemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...
