Kim, Minsoo published the artcileStructure activity relationship exploration of 5-hydroxy-2-(3-phenylpropyl)chromones as a unique 5-HT_2B receptor antagonist scaffold, Computed Properties of 620-20-2, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(21), 127511, database is CAplus and MEDLINE.

Antagonists for the serotonin receptor 2B (5-HT_2B) have clin. applications towards migraine, anxiety, irritable bowl syndrome, and MDMA abuse; however, few selective 5-HT_2B antagonists have been identified. Previous studies from these labs identified a natural product, 5-hydroxy-2-(2-phenylethyl)chromone (5-HPEC, 2) as the first non-nitrogenous ligand for the 5-HT_2B receptor. Studies on 5-HPEC optimization led to the identification of 5-hydroxy-2-(3-phenylpropyl)chromone (5-HPPC, 3), which showed a tenfold improvement in binding affinity over 2 at 5-HT_2B. This study aimed to further improve receptor pharmacol. of this unique scaffold. Guided by mol. modeling studies modifications at the C-3′ and C-4′ positions of 3 were made to probe their effects on ligand binding affinity and efficacy. Among the derivatives synthesized 5-hydroxy-2-(3-(3-cyanophenyl)propyl)chromone (5-HCPC, 3d) showed the most promise with a multifold improvement in binding affinity (pK_i = 7.1 ± 0.07) over 3 with retained antagonism.

Adamiak, Lisa published the artcilePeptide Brush Polymers and Nanoparticles with Enzyme-Regulated Structure and Charge for Inducing or Evading Macrophage Cell Uptake, SDS of cas: 6249-56-5, the publication is ACS Nano (2017), 11(10), 9877-9888, database is CAplus and MEDLINE.

Cellular uptake by macrophages and ensuing clearance by the mononuclear phagocyte system stands as a significant biol. barrier for nanoparticle therapeutics. While there is a growing body of work investigating the design principles essential for imparting nanomaterials with long-circulating characteristics and macrophage evasion, there is still a widespread need for examining stimuli-responsive systems, particularly well-characterized soft materials, which differ in their physiochem. properties prior to and after an applied stimulus. In this work, we describe the synthesis and formulation of polymeric nanoparticles (NPs) and soluble homopolymers (Ps) encoded with multiple copies of a peptide substrate for proteases. We examined the macrophage cell uptake of these materials, which vary in their peptide charge and conjugation (via the N- or C-terminus). Following treatment with a model protease, thermolysin, the NPs and Ps undergo changes in their morphol. and charge. After proteolysis, zwitterionic NPs showed significant cellular uptake, with the C-terminus NP displaying higher internalization than its N-terminus analog. Enzyme-cleaved homopolymers generally avoided assembly and uptake, though at higher concentrations, enzyme-cleaved N-terminus homopolymers assembled into discrete cylindrical structures, whereas C-terminus homopolymers remained dispersed. Overall, these studies highlight that maintaining control over NP and polymer design parameters can lead to well-defined biol. responses.

Binisti, Carine published the artcileStructure-activity relationships in platelet activating factor. 9. From PAF-antagonism to PLA₂ inhibition, Synthetic Route of 18791-02-1, the publication is Journal of Lipid Mediators and Cell Signalling (1997), 15(2), 125-144, database is CAplus and MEDLINE.

Novel acylated piperazines substituted at the 2-position by C_4-17 alkyl groups, analogs of known PAF-antagonists, were prepared by standard methods. These new compounds inhibited various secretory PLA₂s, with IC₅₀‘s in the μmol range. SAR evaluation showed that inhibition of secretory PLA₂ depends on the length of the alkyl chain, with an optimum for 13 to 17 carbons, which is in agreement with X-ray crystallog. and NMR (NMR) studies on the active site of PLA₂s, and that a free nitrogen on the piperazine ring is required to ensure a good inhibitory potency.

Because of their inherent instability, hydropersulfides (RSSH) must be generated in situ using precursors, but very few physiol. useful RSSH precursors have been developed to date. In this work, we report the design, synthesis, and evaluation of novel S-substituted thioisothioureas as RSSH precursors. These water-soluble precursors show efficient and controllable release of RSSH under physiol. conditions.
