Chen, Yun published the artcileDesign and synthesis of Imidazo[1,2-b]pyridazine IRAK4 inhibitors for the treatment of mutant MYD88 L265P diffuse large B-cell lymphoma, Synthetic Route of 73874-95-0, the main research area is imidazopyridazine preparation docking SAR cytotoxicity IRAK4 inhibitor human; Antitumor agents; Diffuse large B-cell lymphoma; Drug design; Imidazo[1,2-b]pyridazine; Interleukin-1 receptor associated kinase 4.

The design, synthesis and structure-activity relationships of imidazo[1,2-b]pyridazines I [R = 2-aminoethyl, 3-amino-piperidin-1-yl, piperazin-1-yl, etc.; R1 = CF2, CF3, CN, etc.; R2 =Me, Et, iPr, etc.; R3 = H, Me] as potent IRAK4 inhibitors was reported. The representative compound I [R = amino-piperidin-3-yl; R1 = CF2; R2 = Me; R3 = H] exhibited excellent IRAK4 potency (IRAK4 IC50 = 1.3 nM) and favorable kinase selectivity profile. It demonstrated cellular selectivity for activated B cell-like (ABC) subtype DLBCL with MYD88 L265P mutation in cytotoxicity assay. The kinase inhibitory efficiency of compound I [R = amino-piperidin-3-yl; R1 = CF2; R2 = Me; R3 = H] was further validated by western blot anal. of phosphorylation of IRAK4 and downstream signaling in OCI-LY10 and TMD8 cells. Besides, combination of compound I [R = amino-piperidin-3-yl; R1 = CF2; R2 = Me; R3 = H] and BTK inhibitor ibrutinib synergistically reduced the viability of TMD8 cells. These results indicated that compound I [R = amino-piperidin-3-yl; R1 = CF2; R2 = Me; R3 = H] could be a promising IRAK4 inhibitor for the treatment of mutant MYD88 DLBCL.

Nguyen, William published the artcileStructure activity refinement of phenylsulfonyl piperazines as antimalarials that block erythrocytic invasion, SDS of cas: 73874-95-0, the main research area is phenyl sulfonyl piperazine preparation antimalarial antitumor lipophilicity SAR; Antimalarial; Erythrocyte invasion; Malaria; Phenylsulfonyl piperazine; Plasmodium.

The optimization and further characterization of the phenylsulfonyl piperazine class I [R = 4-Me, 3-t-Bu, 4-Br, etc.; R1 = pyrrolidin-1-yl, piperidin-1-yl, 1,2,3,4-tetrahydroisoquinolin-2-yl, etc.; X = -(N(CH2)2N(CH2)2)-CH(CH3), -(NCH(CH3)N(CH2)2)-CH(CH3), -(NC(CH3)2N(CH2)2)-CH(CH3), etc.] was described. During the optimization process the functionality required for P. falciparum asexual stage activity was defined and determined the alpha-carbonyl S-Me isomer was important for antimalarial potency. The optimized compounds I also possessed comparable activity against multidrug resistant strains of P. falciparum and displayed weak activity against sexual stage gametocytes. The optimized compounds I blocked erythrocyte invasion consistent with the asexual activity observed and therefore the phenylsulfonyl piperazine analogs described could serve as useful tools for studying Plasmodium erythrocyte invasion.

Li, Na published the artcileStructure-Based Discovery of a Series of NSD2-PWWP1 Inhibitors, Formula: C10H20N2O2, the main research area is imidazole preparation SAR antitumor activity inhibitor.

A series of NSD2-PWWP1 inhibitors I (R = 4-cyanophenyl, 4-cyanonaphthalen-1-yl, 8-cyanoquinolin-5-yl, etc.; R1 = H, OMe, F, Cl, CF3; R2 = H, Me, OMe; R3 = aminomethyl, CHO, 4-aminopiperidin-1-yl, etc.), and further structure-based optimization resulted in a potent inhibitor compound I (R = 4-cyanonaphthalen-1-yl; R1 = R2 = Me; R3 = 4-aminopiperidin-1-yl) (II), that has high selectivity toward the NSD2-PWWP1 domain were reported. The detailed biol. evaluation revealed that compound II can bind to NSD2-PWWP1 and then affect the expression of genes regulated by NSD2. The current discovery will provide a useful chem. probe to the future research in understanding the specific regulation mode of NSD2 by PWWP1 recognition and pave the way to develop potential drugs targeting NSD2 protein.

Zhang, Xiangyu published the artcileDesign, synthesis and biological evaluation of novel benzofuran derivatives as potent LSD1 inhibitors, Synthetic Route of 73874-95-0, the main research area is cyanophenyl aminomethyl arylbenzofuran preparation; LSD1 cytochromep450 inhibition SAR antitumor cytotoxicity docking apoptosis induction; Anti-lung cancer; Benzofuran derivatives; LSD1; Molecular docking; Structure-activity relationships.

A series of benzofurans I [R = 3-aminopropylamino, pyrrolidin-3-ylamino, piperazin-1-yl, etc.; Ar = pyrimidin-5-yl, p-tolyl, 1-methylindazol-5-yl, etc.] were designed, synthesized and biochem. evaluated as LSD1 inhibitors based on scaffold hopping and conformational restriction strategy. Most of the compounds I potently suppressed the enzymic activities of LSD1 and potently inhibited tumor cells proliferation. In particular, the representative compound I [R = (3S)-3-amino-1-piperidyl; Ar = p-tolyl] exhibited excellent LSD1 inhibition at the mol. levels with IC50 = 0.065μM, as well as anti-proliferation against MCF-7, MGC-803, H460, A549 and THP-1 tumor cells with IC50 values of 2.90 ± 0.32, 5.85 ± 0.35, 2.06 ± 0.27, 5.74 ± 1.03 and 6.15 ± 0.49μM, resp. The binding modes of these compounds I were rationalized by mol. docking. Meanwhile, a preliminary druggability evaluation showed that compound I [R = (3S)-3-amino-1-piperidyl; Ar = p-tolyl] displayed favorable liver microsomal stability and weak inhibitory activity against CYPs at 10μM. Remarkably, H460 xenograft tumors studies revealed that compound I [R = (3S)-3-amino-1-piperidyl; Ar = p-tolyl] demonstrated robust in-vivo antitumor efficacy without significant side effects. All the results demonstrated that compound I [R = (3S)-3-amino-1-piperidyl; Ar = p-tolyl] could represent a promising lead for further development.
