Aim: There is little information available on the monoamine oxidase isoform selectivity of N-alkyl harmine analogs, which exhibit a myriad of activities including MAO-A, DYRK1A and cytotoxicity to several select cancer cell lines.
Results: Compounds 3e and 4c exhibited an IC of 0.83 ± 0.03 and 0.43 ± 0.002 μM against MAO-A and an IC of 0.26 ± 0.04 and 0.36 ± 0.001 μM against MAO-B, respectively. Molecular docking studies revealed π-π interactions between the synthesized molecules and aromatic amino acid residues. Conclusion & future perspective: The current study delineates the structural requirements for MAO-A selectivity and such information may be helpful in designing selective analogs for kinase, DYRK1A and harmine-based cytotoxics without apparent MAO enzyme inhibition.

Human UDP-glucuronosyltransferases (UGTs) are pivotal phase II metabolic enzymes facilitating the transfer of glucuronic acid from UDP-glucuronic acid (UDPGA) to various substrates. UGTs are classic type I transmembrane glycoproteins, mainly localized in the endoplasmic reticulum (ER) membrane. This review comprehensively explores UGTs, encompassing gene expression, functional characteristics, substrate specificity, and metabolic mechanisms.

Linezolid, a widely used oxazolidinone antibiotic, exhibits potent activity against resistant bacterial infections but is associated with serotonergic toxicity, primarily due to its inhibition of monoamine oxidase (MAO). MAOs, consisting of MAO-A and MAO-B isoforms, play crucial roles in neurotransmitter metabolism, with implications for neurodegenerative disorders like Parkinson's and Alzheimer's diseases. This study aims to optimize Linezolid's structure to transform it into a selective MAO-B inhibitor.

Gastric cancer (GC) is one of the most prevalent malignant tumors in the world and has an extremely poor prognosis. Regulator of calcineurin 1 (RCAN1), a known tumor suppressor in various cancers, has an undefined role in the proliferation and metastasis of GC. Primary tumor and paired normal gastric tissues were collected from 77 patients with GC for evaluating the mRNA levels of 3 RCAN1 transcripts.

The permeability transition (PT) is a permeability increase of the mitochondrial inner membrane causing mitochondrial swelling in response to matrix Ca. The PT is mediated by regulated channel(s), the PT pore(s) (PTP), which can be generated by at least two components, adenine nucleotide translocator (ANT) and ATP synthase. Whether these provide independent permeation pathways remains to be established.

Tumor-associated human carbonic anhydrases (hCAs), particularly isoforms hCA IX and hCA XII, are overexpressed in hypoxic regions of solid tumors and play a crucial role in regulating pH homeostasis, promoting cancer cell survival and enhancing invasiveness. These enzymes have emerged as promising therapeutic targets in cancer treatment, including photothermal therapy (PTT). PTT is a minimally invasive technique that uses light-absorbing agents to convert near-infrared (NIR) light into heat, effectively inducing localized hyperthermia and promoting cancer cell apoptosis.
