Scalemic natural products

open access: yesNatural Product Reports, 2023
In natural products, a low optical purity is not generally associated with a sloppy enzymatic activity, but rather with the co-expression of antipodal enzymes/directing proteins or, alternatively, with erosion by enzymatic or spontaneous reactions.

Natural Diagonal Riemannian Almost Product and Para-Hermitian Cotangent Bundles [PDF]

open access: yes, 2009
We obtain the natural diagonal almost product and locally product structures on the total space of the cotangent bundle of a Riemannian manifold. We find the Riemannian almost product (locally product) and the (almost) para-Hermitian cotangent bundles of

Natural Products for Medicine [PDF]

open access: yesJournal of Biomedicine and Biotechnology, 2012
Throughout human history, natural products—including terrestrial plants, animal products, marine organisms, and products of microorganismal fermentation—have been used in traditional medicines. This historical experience with natural products as therapeutic agents has evolved to sophisticated isolation of active chemical entities from ...

A Natural Love of Natural Products [PDF]

open access: yesThe Journal of Organic Chemistry, 2008
Recent research on the chemistry of natural products from the author's group that led to the receipt of the ACS Ernest Guenther Award in the Chemistry of Natural Products is reviewed. REDOR NMR and synthetic studies established the T-taxol conformation as the bioactive tubulin-binding conformation, and these results were confirmed by the synthesis of ...

Natural products genomics [PDF]

open access: yesMicrobial Biotechnology, 2008
Secondary metabolites (or natural products) are often synthesized by multi‐modular, multi‐domain proteins called non‐ribosomal peptide synthetases (NRPS) and polyketide synthases (PKS). Various well‐known metabolites produced by microorganisms are listed in Table 1, and examples of structures are shown in Fig. 1. In particular, Streptomyces species are

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]

open access: yes, 2016
The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the
