The discovery of a series of substituted diarylether compounds as retinoic acid related orphan receptor γt (RORγt) agonists is described. Compound 1 was identified from deck mining as a RORγt agonist. Hit-to-lead optimization led to the identification of lead compound 5, which possesses improved potency (10x). Extensive SAR exploration led to the identification of a potent and selective compound 22, that demonstrated an improved pharmacokinetic profile and a dose-dependent pharmacodynamic response. However, when dosed in a MC38 syngeneic tumor model, no evidence of efficacy was observed

Schuster, Ingeborg I. published the artcileEnhancement of the resonance interaction of out-of-plane methoxy groups by ortho-substituents in crowded anisoles, COA of Formula: C10H14O, the publication is Journal of Organic Chemistry (1988), 53(25), 5819-25, database is CAplus.

The ¹⁷O and ¹³C NMR chem. shifts of substituted anisoles provide evidence that the resonance interaction of methoxy groups which are perpendicular to the aromatic ring in crowded anisoles is influenced, to varying degrees, by ortho substituents. Enhancement of methoxy-to-aryl electron delocalization, brought about by these groups, follows the order isopropyl < ethyl < methyl << methoxy (in-plane) < tert-Bu. By an anal. of the mol. structures of several 3,5-dialkylanisic acids, related to 2,6-dialkylanisoles, this order becomes explicable in terms of repulsions between the lone pair electrons of the methoxy oxygen and bonding electrons of the proximate substituents. Methoxy groups that lie in the mol. plane are not similarly affected by neighboring substituents.

To confront a disease like Alzheimer’s disease having complex pathogenesis, development of multitarget-directed ligands has emerged as a promising drug discovery approach. In our endeavor towards the development of multitarget-directed ligands for Alzheimer’s disease, a series of indoloquinoxaline derivatives were designed and synthesized. In vitro cholinesterase inhibition studies revealed that all the synthesized compounds exhibited moderate to good cholinesterase inhibitory activity. 6-(6-(Piperidin-1-yl)hexyl)-6H-indolo[2,3-b]quinoxaline was identified as the most potent and selective BuChE inhibitor (IC₅₀ = 0.96μM, selectivity index = 0.17) that possessed 2 fold higher BuChE inhibitory activity compared to the com. approved reference drug donepezil (IC₅₀ = 1.87μM). Moreover, compound is also endowed with self-induced Aβ1-42 aggregation inhibitory activity (51.24% inhibition at 50μM concentration). Some of the compounds of the series also displayed moderate anti-oxidant activity. To perceive a putative binding mode of the compound, mol. docking studies were carried out, and the results pointed out significant interactions of compound with the enzymes in the binding sites of cholinesterases as well as Aβ1-42. Addnl., compound exhibited favorable in silico ADMET properties. Put together these findings project compound as a potential multitarget-directed ligand in the direction of developing novel anti-AD drugs.Communicated by Ramaswamy H.

Young, Trudye A. published the artcileA pramoxine-based anti-itch lotion is more effective than a control lotion for the treatment of uremic pruritus in adult hemodialysis patients, COA of Formula: C17H28ClNO3, the publication is Journal of Dermatological Treatment (2009), 20(2), 76-81, database is CAplus and MEDLINE.

Objective: The objective of this study was to evaluate the efficacy of a com. available anti-itch lotion containing 1% pramoxine hydrochloride vs. control lotion in the treatment of uremic pruritus in adult hemodialysis patients. Methods: This was a randomized, double-blind, controlled comparative trial set in a community hemodialysis center. The study population comprised 28 individuals (mean age 53.5) with moderate to severe uremic pruritus who had been receiving hemodialysis for at least 3 mo. All participants were recruited from one community hemodialysis center. Topical anti-itch lotion containing 1% pramoxine was applied twice daily to all affected areas of pruritus for 4 wk. The main outcome measure was a reduction in itch intensity. Secondary outcomes included increases in the investigator’s global assessment and improvement in skin hydration. Results: There was a 61% decrease in itch intensity in the treatment group, whereas a 12% reduction in itch intensity was observed in the control group. The rate of decline in itching was also greater in the treatment arm vs. the control arm. No significant differences were displayed in other studied disease-related variables. Conclusion: Our study shows that individuals using pramoxine 1% lotion experienced a reduction in pruritus to a greater degree than those using the control lotion. This safe, convenient and effective topical lotion may potentially benefit the large number of patients affected by pruritus associated with end-stage renal disease.

Neurokinin B (NKB) regulates the release of gonadotropin-releasing hormone (GnRH) via activation of the neurokinin-3 receptor (NK3R). We evaluated the biol. stability of NK3R selective agonists to develop novel NK3R agonists to regulate reproductive functions. On the basis of degradation profiles, several peptidomimetic derivatives were designed. The modification of senktide with (E)-alkene dipeptide isostere generated a novel potent NK3R agonist with high stability and prolonged bioactivity.

Noguchi, Taro published the artcileStructure-activity relationship study of neurokinin-3 receptor agonists, SDS of cas: 77128-73-5, the publication is Peptide Science (2013), 189-190, database is CAplus.

A symposium report. Neurokinin B (NKB) is a member of the tachykinin peptide family. NKB and the cognate receptor, neurokinin-3 receptor (NK3R), are involved in the secretion of the gonadotropin releasing hormone (GnRH) by kisspeptin neurons. Our SAR study demonstrated that NK3R-selectivity was improved by modifications of Phe⁵ and Val⁷ in NKB and the corresponding residues in the tachykinin peptides.
