Abstract: HSV disease is distributed worldwide. Anti-herpesvirus drugs are a problem in clin. settings, particularly in immunocompromised individuals undergoing herpes simplex virus type 1 infection. In this work, 4-substituted-1,2,3-1H-1,2,3-triazole linked nitroxyl radical derived from TEMPOL were synthesized, and their ability to inhibit the in vitro replication of HSV-1 was evaluated. The nitroxide derivatives were characterized by IR spectroscopy and elemental anal., and three of them had their crystal structures determined by single-crystal X-ray diffraction. Four hybrid mols. showed important anti-HSV-1 activity with IC₅₀ values ranged from 0.80 to 1.32μM. In particular, one of the nitroxide derivatives was more active than Acyclovir (IC₅₀ = 0.99μM). All compounds tested were more selective inhibitors than the reference antiviral drug. Among them, two compounds were 4.5 (IC₅₀ 0.80μM; selectivity index CC₅₀/IC₅₀ 3886) and 7.7 times (IC₅₀ 1.10μM; selectivity index CC₅₀/IC₅₀ 6698) more selective than acyclovir (IC₅₀ 0.99μM; selectivity index CC₅₀/IC₅₀: 869). These nitroxide derivatives may be elected as leading compounds due to their antiherpetic activities and good selectivity.

Spinal muscular atrophy (SMA), a rare neuromuscular disorder, is the leading genetic cause of death in infants and toddlers. SMA is caused by the deletion or a loss of function mutation of the survival motor neuron 1 (SMN1) gene. In humans, a second closely related gene SMN2 exists, however it codes for a less stable SMN protein. In recent years, significant progress has been made toward disease modifying treatments for SMA by modulating SMN2 pre-mRNA splicing. Herein, we describe the discovery of LMI070/branaplam, a small mol. that stabilizes the interaction between the spliceosome and SMN2 pre-mRNA. Branaplam (1) originated from a high-throughput phenotypic screening hit, pyridazine 2, and evolved via multi-parameter lead optimization. In a severe mouse SMA model, branaplam treatment increased full-length SMN RNA and protein levels, and extended survival. Currently, branaplam is in clin. studies for SMA.

Recent studies on 3,6-diphenylated imidazopyridazines have demonstrated impressive in vitro activity and in vivo efficacy in mouse models of malaria infection. Herein, we report the synthesis and antiplasmodium evaluation of a new series of amidated analogs and demonstrate that these compounds potently inhibit Plasmodium phosphatidylinositol-4-kinase (PI4K) type IIIβ while moderately inhibiting cyclic guanidine monophosphate (cGMP)-dependent protein kinase (PKG) activity in vitro. Using in silico docking, we predict key binding interactions for these analogs within the ATP (ATP)-binding site of PI4K and PKG, paving the way for structure-based optimization of imidazopyridazines targeting both Plasmodium PI4K and PKG. While several derivatives showed low nanomolar antiplasmodium activity (IC₅₀ < 100 nM), some compounds, including piperazine analog I, resulted in strong dual PI4K and PKG inhibition. The compounds also demonstrated transmission-blocking potential, evident from their potent inhibition of early- and late-stage gametocytes. Finally, the current compounds generally showed improved aqueous solubility and reduced hERG (human ether-a-go-go-related gene) channel inhibition.

Chen, Zimin;Zheng, Songlin;Wang, Zijie;Liao, Zixuan;Yuan, Weiming research published 《 Electron Donor-Acceptor Complex Enabled Photocyanation of Tertiary Amines with a Stable and User-Friendly Cyanobenziodoxolone Reagent》, the research content is summarized as follows. A visible light-induced photocyanation of tertiary amines e.g., 1-((trimethylsilyl)methyl)piperidine by a stable, less-toxic and user-friendly CN reagent cyanobenziodoxolone (CBX) was developed. This cyanation process does not require any photocatalyst, oxidant, base or additives, and represents a set of extremely mild and succinct reaction conditions and a broad substrate scope. In addition to the frequently used N-aryl amine derivatives e.g, 2-thiomorpholinoacetonitrile, more challenging tertiary aliphatic amines (modified by a α-silyl substituent) can also be photocyanated smoothly. Mechanistic studies reveal that the cyanation reaction is enabled by an electron donor-acceptor (EDA) complex formed by the interaction between the amine and the cyanobenziodoxolone reagent.

Single-electron N-heterocyclic carbene (NHC) catalysis has gained attention recently for the synthesis of C-C bonds. Guided by d. functional theory and mechanistic analyses, authors report the light-driven synthesis of aliphatic and α-amino ketones using single-electron NHC operators. Computational and exptl. results reveal that the reactivity of the key radical intermediate is substrate-dependent and can be modulated through steric and electronic parameters of the NHC. Catalyst potential is harnessed in the visible-light driven generation of an acyl azolium radical species that underwent selective coupling with various radical partners to afford diverse ketone products. This methodol. is showcased in the direct late-stage functionalization of amino acids and pharmaceutical compounds, highlighting the utility of single-electron NHC operators.
