Article Abstract

Monoamine oxidase B (MAO-B) metabolizes monoamines such as dopamine regarding neural transmission and controls its level in the mammalian's brain. When MAO-B metabolizes dopamine abnormally, normal neurotransmission does not occur, and central nervous system disorders such as Parkinson's disease may develop. Although several MAO inhibitors have been developed, most of them have no selectivity between monoamine oxidase A (MAO-A) and MAO-B, or they work irreversibly against the enzyme. This report describes the first case of screening of -arylated heliamine derivatives to develop novel MAO-B selective inhibitors that can be synthesized concisely by microwave-assisted Pd nanoparticle-catalyzed Buchwald-Hartwig amination. We discovered that the derivatives , , and display inhibitory activity against MAO-B with IC values of 1.55, 13.5, and 5.08 μM, respectively.

Inhibition of human monoamine oxidase B (hMAO-B) to prevent both oxidative stress and lipid metabolism disorders, which are high-risk factors for pathogenesis of atherosclerosis, is a potential strategy for the treatment of atherosclerosis. In this study, we have explored a series of C-3 nitrothiophene substituted thiochromone analogues that showed good to excellent potency against hMAO-B. The strategy of introduction the nitro-group into thiophene linker, which contributes pivotal interactions with Cys172, significantly improved the potency and selectivity of these compounds.

Pulmonary toxicity is a serious yet frequently under-recognized complication of antidepressant therapy. With the continued rise in prescriptions, awareness of potential respiratory adverse effects is crucial. This review outlines documented cases of lung injury linked to various antidepressant classes, including selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), atypical antidepressants, serotonin modulators, tricyclic antidepressants (TCAs), and monoamine oxidase inhibitors (MAOIs).

The interaction of antirenalase antibodies with full-length recombinant human renalases RNLS1 and RNLS2, as well as fragments of these proteins encoded by alternative exons 9 and 10 and expressed as fusion proteins with dihydrofolate reductase (DHFR) in Escherichia coli cells has been investigated. In this study we used custom made polyclonal antibodies to the full-length recombinant RNLS1 (amino acid residues (aa) 1-342), created at our request, as well as commercially available monoclonal antibodies to the renalase fragment (aa - 18-342), specific for the RNLS1 isoform and its C-terminal sequence encoded by exon 9. According to Western blot analysis, the antibodies interacted not only with recombinant RNLS1 and RNLS2 preparations, but also with fusion proteins containing C-terminal sequences specific for these isoforms (DHFR-RNLS-9ex and DHFR-RNLS-10ex).
