Increasing space-time-yield, carbon-conversion-efficiency and carbon substrate flexibility in the production of fine chemicals

Fascinating discovery from BASF on increasing space-time-yield, carbon-conversion-efficiency, and carbon substrate flexibility in the production of fine chemicals. They found a positive effect of increased cAMP levels and/or manipulating the PTS system on the above characteristics achieved by de-regulating adenylate cyclase cyaa by deleting the C-terminal regulatory region leading to increased cAMP levels or deleting the Crr protein activity (carbohydrate repression resistance) which regulates the carbohydrate utilization system. Both lead to increased 2-fucosyllactoe and 6-sialyllactose production (human milk oligosaccharides) and increase carbohydrate usage.

Fucosyltransferase-specific inhibition using fucose mimetics

Fascinating joint invention by Università degli Studi di Firenze and Florida International University – Robert Sackstein MD,PhDBarbara Richichi, and Kyle Martin.
The specific glycomimetic fucosyltransferase inhibitors created are proposed for treatment of a variety of diseases, like acute inflammatory disease, chronic inflammatory disease, diabetes, cystic fibrosis, or a cancer via a modification of fucosylated cell surface glycoconjugates.

Sugar-decorated carbon dots: a novel tool for targeting immunomodulatory receptor

Griffith University (Oren CooperDechao ChenThomas HaselhorstJoseph Tiralongo et al) and University of Bremen released common findings on creating multivalent siglec probes through the decoration of α(2,6)-sialyllactose ligands on inherently fluorescent carbon dots capable of generating a significant cytotoxic effect on Burkitt’s Lymphoma (BL) Daudi B cells.

Prostate-specific membrane antigen (PSMA) ligands comprising an amylase cleavable linker

Using sugars in a prodrug concept is a fascinating idea as these compounds can bring so much to the table like improve stability, PK, or help in targeting. In this patent from Heidelberg University oligosaccharide conjugated prostate-specific membrane antigens are described where the bonds are cleaved by amylase in the body.
