Natural products (NPs) are very important sources for the development of new drugs. Merrillianone and cycloparvifloralone, isolated from the roots, stems, and fruits of Illicium henryi Diels, are two natural sesquiterpene compounds In continuation of our effort to discover more effective neurotrophic compounds from NPs, a series of novel merrillianone/cycloparvifloralone based esters I (R = MeCH:CHCH:CH, CH₂CH₂Ph, CH₂CH₂COPh, etc.) and II (R = 4-BrC₆H₄CH₂, 2-naphthylmethyl, CH:CHPh, etc.) were prepared and their structures were characterized by ¹H NMR, ¹³C NMR and IR spectral analyses. Furthermore, the spatial structure of compound I (R = CH₂CH₂Ph) was unambiguously confirmed by X-ray crystallog. The neurite outgrowth-promoting activity results indicated that most of the target derivatives exhibited more potent neurite outgrowth-promoting activity than merrillianone and cycloparviforalone. Among all target derivatives, the neurite outgrowth-promoting activity of compounds I (R = MeCH:CHCH:CH) and II (R = MeCH:CHCH:CHMe, 4-FC₆H₄CH₂CH₂) was about 2-fold stronger than that of their precursors merrillianone and cycloparvifloralone, resp. Besides, compounds I (R = MeCH:CHCH:CH) and II (R = MeCH:CHCH:CH) displayed relatively low cytotoxicity to normal GES-1 cells. Moreover, these derivatives had good hydrolytic stability. Finally, some interesting results of the structure-activity relationships (SARs) were also discussed. This work will pave the way for the development of merrillianone/cycloparvifloralone derivatives as potential neurotrophic agents.

Yvonne;Whiting, Paul;Fish, Paul V. research published 《 Design of a Potent, Selective, and Brain-Penetrant Inhibitor of Wnt-Deactivating Enzyme Notum by Optimization of a Crystallographic Fragment Hit》, the research content is summarized as follows. Notum is a carboxylesterase that suppresses Wnt signaling through deacylation of an essential palmitoleate group on Wnt proteins. There is a growing understanding of the role Notum plays in human diseases such as colorectal cancer and Alzheimer’s disease, supporting the need to discover improved inhibitors, especially for use in models of neurodegeneration. Here, authors have described the discovery and profile of I (ARUK3001185) as a potent, selective, and brain-penetrant inhibitor of Notum activity suitable for oral dosing in rodent models of disease. Crystallog. fragment screening of the Diamond-SGC Poised Library for binding to Notum, supported by a biochem. enzyme assay to rank inhibition activity, identified II (R = H) and II (R = Cl) as a pair of outstanding hits. Fragment development of II delivered I that restored Wnt signaling in the presence of Notum in a cell-based reporter assay. Assessment in pharmacol. screens showed I to be selective against serine hydrolases, kinases, and drug targets.

Results: Results of in silico studies indicated that quinazolinone derivatives exhibited a good affinity towards the active site of PARP-1. Out of all synthesized compounds, SVA-11 exhibited a maximum dock score (-10.421). Results of ADME studies indicated the suitability of synthesized compounds as drug candidates. Conclusion: The synthesized compounds showed better docking scores than reference drug veliparib. Furthermore, they exhibited favorable ADME profile.
