AI Article Synopsis
Article Abstract
Efficient one-pot five-component synthetic protocols for highly functionalized tetrahydropyridines (THPs) and their biological evaluation have been illustrated. Synthesis of novel functionalized tetrahydropyridines containing differential substitutions at 2,6-positions has been achieved via a modified MCR. Cytotoxic studies of 23 synthesized compounds have been carried out against three different cell lines, namely A-549, HeLa and HepG2, wherein some compounds have displayed appreciable cytotoxicity. Further, investigation of enzyme inhibition by the synthesized THPs has been carried out against four members of M1 family aminopeptidases. Several compounds have selectively inhibited only one member of this enzyme family i.e., human puromycin sensitive aminopeptidase (hPSA). Among the compounds; 4b, 9b, 9e and 10a demonstrated best inhibition against hPSA.

Intracerebral hemorrhage (ICH) is a severe stroke subtype with high mortality and limited therapeutic options. The blood-brain barrier (BBB) breakdown post-ICH exacerbates secondary brain injury, highlighting the need for targeted therapies to preserve the BBB integrity. We aim to investigate the role of the Sphk1/S1P pathway in BBB breakdown following ICH and to evaluate the therapeutic potential of Sphk1 inhibition in mitigating this breakdown.

Accumulating evidence indicates that inherited astrocyte dysfunction can be a primary trigger for epilepsy development; however, the available data are rather limited. In addition, astrocytes are considered as a perspective target for the design of novel and improvement of the existing antiepileptic therapy. Piracetam and related nootropic drugs are widely used in the therapy of various epileptic disorders, but detailed mechanisms of racetams action and, in particular, their effects on glial functions are poorly understood.

Background: The correlation between serum cotinine and fatty liver index (FLI) needs further investigation for the early identification, prevention, and treatment of metabolic dysfunction-associated steatotic liver disease (MASLD).
Methods: Data from the NHANES database spanning from March 2017 to 2018 was used to perform the population-based study to assess the relationship between serum cotinine and FLI. A variance estimation strategy was applied to address the data volatility.

Glycyrrhetinic acid (GA) possesses various pharmacological effects, including anti-inflammatory, anti-tumor, and anti-viral properties. However, its clinical application is limited by poor solubility and low oral bioavailability. Polymers play a crucial role in pharmaceutical formulations, particularly as matrices in excipients to enhance the solubility, bioavailability, and stability of active pharmaceutical ingredients.

Background: Cystic fibrosis (CF) is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) channel. For people with CF (pwCF) affected by the most common pathogenic variant F508del, a tritherapy, named Trikafta/Kaftrio (ETI: elexacaftor (VX-445) /tezacaftor (VX-661) / ivacaftor (VX-770)) was successfully developed. However, in CF airway epithelial cells the calcium homeostasis is also disturbed; it is observed an increased calcium mobilization in CF cells compared to non-CF cells.
