Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

Polymer International, EarlyView.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Enzymology of Pyran Ring A Formation in Salinomycin Biosynthesis [PDF]

Angewandte Chemie, 2015
AbstractTetrahydropyran rings are a common feature of complex polyketide natural products, but much remains to be learned about the enzymology of their formation. The enzyme SalBIII from the salinomycin biosynthetic pathway resembles other polyether epoxide hydrolases/cyclases of the MonB family, but SalBIII plays no role in the conventional cascade of

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Stimulation of Antibody Formation by Pyran Copolymer

Experimental Biology and Medicine, 1970
SummaryPyran copolymer, administered with sheep red blood cells to mice, enhances the early rate of appearance of antibody-forming spleen cells. Although the cytotoxicity and pyrogenicity of pyran and bacterial endotoxins are similar, pyran, in contrast to endotoxin, does not trigger a nonspecific initiation of antibody formation; it only enhances ...

Structure‐Controlled Cyclopentadithiophene Derived Non‐Fullerene Acceptors for Efficient Near‐Infrared Organic Photodetectors

Small, EarlyView.
This work demonstrates high‐performance solution‐processed NIR OPDs using DTP‐ and DTTP‐based NFAs (OC and SC), where donor‐core engineering enables tunable absorption and balanced optoelectronic properties; notably, DTP‐based devices achieve broad NIR response, low dark current, and high detectivity, highlighting their potential for advanced NIR ...
