In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Optimization of WZ4003 as NUAK inhibitors against human colorectal cancer, published in 2021-01-15, which mentions a compound: 4045-24-3, mainly applied to pyrimidine human colorectal cancer anticancer apoptosis; AMP-Activated protein kinase (AMPK); Colorectal cancer; NUAK; WZ4003 derivatives, COA of Formula: C6H13NO.

NUAK, the member of AMPK (AMP-activated protein kinase) family of protein kinases, is phosphorylated and activated by the LKB1 (liver kinase B1) tumor suppressor protein kinase. Recent work has indicated that NUAK1 is a key component of the antioxidant stress response pathway, and the inhibition of NUAK1 will suppress the growth and survival of colorectal tumors. As a promising target for anticancer drugs, few inhibitors of NUAK were developed. With this goal in mind, based on NUAK inhibitor WZ4003, a series of derivatives has been synthesized and evaluated for anticancer activity. Compound I, a derivative of WZ4003 by removing a methoxy group, was found to be the most potential one with stronger inhibitory against NUAK1/2 enzyme activity, tumor cell proliferation and inducing apoptosis of tumor cells. By in vivo efficacy evaluations of colorectal SW480 xenografts, I suppresses tumor growth more effectively with an excellent safety profile in vivo and is therefore seen as a suitable candidate for further investigation.

By employing a radical process, enolizable aldehydes were utilized as substrates in the three-component radical homo-Mannich reaction for the streamlined synthesis of γ-amino-carbonyl compounds. The electrophilic radicals were generated from thiols HSCHR1C(O)R2 (R1 = H, Me; R2 = Me, EtO, PhCH2O, 1-adamantyl, Et2N, etc.) via the desulfurization process facilitated by visible-light, and then added to the electron-rich double bonds of enamines, formed in-situ from aldehydes or ketones R3CH2C(O)R4 [R3 = H, Et, MeSCH2, Ph, PhCH2, etc., R4 = H; R3 = H, R4 = Ph, 3-FC6H4, etc.; R3R4 = (CH2)5, CH2CHPhCH2CH2, CH2N(CH2Ph)CH2CH2, etc.] and amines R5NHR6 [R5 = Me, R6 = H2C:CHCH2, PhCH2, cyclohexyl, etc.; R5 = PhCH2, R6 = PhCH2, EtO2CCH2, etc.; R5R6 = (CH2)4, CHPh(CH2)3, etc.] to provide the products I in a single step. The broad scope, mild conditions, high functional group tolerance, and modularity of this metal-free approach for the synthesis of complex tertiary amine scaffolds will likely be of great utility to chemists in both academia and industry.

Reference of 4-Methoxypiperidine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Methoxypiperidine, is researched, Molecular C6H13NO, CAS is 4045-24-3, about Discovery of a Novel and Brain-Penetrant O-GlcNAcase Inhibitor via Virtual Screening, Structure-Based Analysis, and Rational Lead Optimization.

O-GlcNAcase (OGA) has received increasing attention as an attractive therapeutic target for tau-mediated neurodegenerative disorders; however, its role in these pathologies remains unclear. Therefore, potent chem. tools with favorable pharmacokinetic profiles are desirable to characterize this enzyme. Herein, we report the discovery of a potent and novel OGA inhibitor, compound 5i, comprising an aminopyrimidine scaffold, identified by virtual screening based on multiple methodologies combining structure-based and ligand-based approaches, followed by sequential optimization with a focus on ligand lipophilicity efficiency. This compound was observed to increase the level of O-GlcNAcylated protein in cells and display suitable pharmacokinetic properties and brain permeability. Crystallog. anal. revealed that the chem. series bind to OGA via characteristic hydrophobic interactions, which resulted in a high affinity for OGA with moderate lipophilicity. Compound 5i could serve as a useful chem. probe to help establish a proof-of-concept of OGA inhibition as a therapeutic target for the treatment of tauopathies.
