The present and the future role of biochemistry in the search for a new therapeutic agent is reviewed. It is stated that the great importance of the various disciplines of biochemistry, including pathobiochemistry and pharmacological biochemistry, is presently recognized, and the involvement of biochemistry in drug research is increasing. Biochemistry at the present time and in the future will utilize the already known basic biological principles for the new development of new and more useful medicines. It is emphasized that the limiting factor in new drug discovery today, however, is the lack of new basic discoveries in biology.

Prefrontal 5α-reductase 2 mediates male-specific acute stress response.

A key response to acute stress is the increased brain synthesis of the neurosteroid allopregnanolone (AP). Although the rate-limiting step of this reaction is catalyzed by 5α-reductase (5αR), the role of its two primary isoenzymes, 5αR1 and 5αR2, in stress reactivity remains unclear. Here, we found that acute stress led to increased levels of 5αR2, but not 5αR1, in the medial prefrontal cortex (mPFC) of male, but not female, rats.

Until now, Hippo pathway-mediated nucleocytoplasmic translocation has been considered the primary mechanism by which yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) transcriptional coactivators regulate cell proliferation and differentiation via transcriptional enhanced associate domain (TEAD)-mediated target gene expression. In this study, however, we found that TAZ, but not YAP, is associated with the Golgi apparatus in macrophages activated via Toll-like receptor ligands during the resolution phase of inflammation. Golgi-associated TAZ enhanced vesicle trafficking and secretion of proinflammatory cytokines in M1 macrophage independent of the Hippo pathway.

Ginsenosides are the most important secondary metabolites of ginseng. Ginseng has developed certain insect resistance properties during the course of evolutionary environmental adaptation. However, the mechanism underlying the insect resistance of ginseng is poorly understood.

Ginsenoside Rh2(S) is well-known for its therapeutic potential against diverse conditions, including some cancers, inflammation, and diabetes. The enzymatic activity of uridine diphosphate glycosyltransferase 51 (UGT51) from Saccharomyces cerevisiae plays a pivotal role in the glycosylation process between UDP-glucose (donor) and protopanaxadiol (acceptor), to form ginsenoside Rh2. However, the catalytic efficiency of the UGT51 has remained a challenging task.

Apigenin, a dietary flavonoid with notable anti-cancer properties, has emerged as a promising candidate for the treatment of neurodegenerative disorders, particularly Alzheimer's disease (AD). While extensively studied for its ability to modulate key molecular pathways in cancers, apigenin also exerts neuroprotective effects by reducing neuroinflammation, protecting neurons from oxidative stress, and enhancing neuronal survival and synaptic plasticity. This dual functionality makes apigenin an intriguing therapeutic option for diseases like AD, where kinase dysregulation plays a central role.
