Development of a Partial Proteolysis Targeting Chimera Library Based on Achiral Cereblon E3 Ligase Ligands and its Application for Bruton's Tyrosine Kinase Degraders

open access: yesChemMedChem, Volume 20, Issue 22, November 18, 2025.
A partial proteolysis targeting chimera (PROTAC) library bearing achiral phenyl dihydrouracil cereblon ligands is prepared. It is then applied to the rapid development of a full PROTAC library targeting Bruton's tyrosine kinase, which can be directly used for screening.

Hypothalamic Astrocytes Exhibit Glycolytic Features Making Them Prone for Glucose Sensing

open access: yesGlia, Volume 73, Issue 11, Page 2253-2272, November 2025.
Main Points Hypothalamic astrocytes versus cortical astrocytes: are more glycolytic due to high Pkm2, Glut1 and Mct4 expression do not exhibit glutamate‐induced glycolysis detect glucose concentration variations via an AMPK sensor with altered lactate production.

Some semicarbazide derivatives and their antimicrobial activity

open access: yesCommunications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1993
Various semicarbazides and thiosemicarbazides (1-5) and their cyclised products, triazoles, oxadiazoles and thiadiazoles (6-9) have been reported to possess antibacterial, antitubercular and antifungal activities. Based on these findings it w as of interest to prepare some new arylsemicarbazide and arylthiosemicarbazide derivatives and to evaluate ...

Batch Synthesis of Primaquine Diphosphate Anti‐Malarial Drug

open access: yesChemistry – A European Journal, Volume 31, Issue 59, October 22, 2025.
According to the WHO, a child under the age of five dies every 2 minutes from malaria in Africa. It is therefore paramount that access and availability of anti‐malarial drugs must be improved. We report a process for the synthesis of Primaquine Diphosphate, where key intermediates were obtained in a much shorter reaction time compared to processes ...

Synthesis of Novel Dihydropyridine‐Iminium Salts Containing a Selenazine Core

open access: yesAsian Journal of Organic Chemistry, Volume 14, Issue 10, October 2025.
An efficient method to develop novel dihydropyrido[3,2‐e][1,3]selenazines iminium salts. A comparative study of the key reagent selenourea towards thiourea and urea was carried out to assess the contribution of chalcogen to the pathway. DFT (density functional theory) calculations have predicted the optimized minimum energy structure for the hybrid ...

Programmable Site‐Selectivity: pH‐Modulated Triazine–Thiol Exchange for Site‐ and Chemoselective Cysteine Labeling

open access: yesChemistryEurope, Volume 3, Issue 5, September 18, 2025.
A pH‐programmable site‐selective cysteine modification in peptides is reported using a triazine–thiol exchange, termed TriTEx. At acidic pH, internal cysteines are targeted while preserving N‐terminal sites; at neutral pH, N‐terminal cysteines are selectively modified via an irreversible S–N shift.
