Piperazine-derived lipid nanoparticles deliver mRNA to immune cells in vivo
In humans, lipid nanoparticles (LNPs) have safely delivered therapeutic RNA to hepatocytes after systemic administration and to antigen-presenting cells after intramuscular injection. However, systemic RNA delivery to non-hepatocytes remains challenging,

The first reported case of piperazine toxicity resembling viral hepatitis is described in a 25-year-old woman. The illness, which was severe, occurred after administration of the drug on two separate occasions. The evidence favors a hypersensitivity mechanism rather than a direct toxic effect of piperazine or its metabolites on the liver.

Synthesis, biological evaluation, and SAR study of novel pyrazole analogues as inhibitors of Mycobacterium tuberculosis: Part 2. Synthesis of rigid pyrazolones [PDF]
Two series of novel rigid pyrazolone derivatives were synthesized and evaluated as inhibitors of Mycobacterium tuberculosis (MTB), the causative agent of tuberculosis. Two of these compounds showed a high activity against MTB (MIC = 4 μg/mL).
