Heng, Hao published the artcileCombining structure- and property-based optimization to identify selective FLT3-ITD inhibitors with good antitumor efficacy in AML cell inoculated mouse xenograft model, SDS of cas: 117738-74-6, the publication is European Journal of Medicinal Chemistry (2019), 248-267, database is CAplus and MEDLINE.

FLT3 mutation is among the most common genetic mutations in acute myeloid leukemia (AML), which is also related with poor overall survival and refractory in AML patients. Recently, FLT3 inhibitors have been approved for AML therapy. Herein, a series of new compounds with pyrazole amine scaffold was discovered, which showed potent inhibitory activity against FLT3-ITD and significant selectivity against both FLT3-ITD and AML cells expressing FLT3-ITD. Compound 46, possessing the most promising cellular activity, blocked the autophosphorylation of FLT3 pathway in MV4-11 cell line. Furthermore, the apoptosis and down regulation of P-STAT5 were also observed in tumor cells extracted from the MV4-11 cell xenografts model upon compound 46 treatment. Compound 46 was also metabolically stable in vitro and suppressed tumor growth significantly in MV4-11 xenografts model in vivo. Compound 46 showed no toxicity to the viscera of mice and caused no decrease in body weight of mice. In conclusion, the results of this study could provide valuable insights into discovery of new FLT3 inhibitors, and compound 46 was worthy of further development as potential drug candidate to treat AML.

Steingruber, H. Sebastian published the artcileConvenient One-Pot Synthesis of 9H-Carbazoles by Microwave Irradiation Employing a Green Palladium-Based Nanocatalyst, HPLC of Formula: 117738-74-6, the publication is Synthesis (2021), 53(21), 4048-4058, database is CAplus.

An efficient palladium-catalyzed tandem reaction for the one-pot synthesis of 9H-carbazoles under microwave irradiation was developed. This approach involves a sequential Buchwald-Hartwig amination and a direct arylation from affordable and inexpensive anilines and 1,2-dihaloarenes. For the development of this purpose, a novel and magnetically recoverable palladium nanocatalyst-supported on a green biochar under ligand-free conditions was used. Compared to other existing palladium-based protocols, the present synthetic methodol. shows a drastic reduction in reaction times and excellent compatibility with different functional groups allowing to obtain a small library of 9H-carbazoles in high yields and with good regioselectivity. This procedure represents the first example in the direct synthesis of carbazoles using a heterogeneous palladium nanocatalyst from com. precursors. To examine the application of this protocol, a direct and scalable synthesis of the bioactive carbazole alkaloid clausenalene from com. available starting materials was described.

Lin, Xianfeng published the artcileDesign and Synthesis of Orally Bioavailable Aminopyrrolidinone Histone Deacetylase 6 Inhibitors, Recommanded Product: Methyl 4-bromo-3-chlorobenzoate, the publication is Journal of Medicinal Chemistry (2015), 58(6), 2809-2820, database is CAplus and MEDLINE.

Histone deacetylase 6 (HDAC6) removes the acetyl group from lysine residues in a number of non-histone substrates and plays important roles in microtubule dynamics and chaperone activities. There is growing interest in identifying HDAC6-selective inhibitors as chem. biol. tools and ultimately as new therapeutic agents. Herein we report the design, synthesis, and phenotypic screening of a novel class of 3-aminopyrrolidinone-based hydroxamic acids as HDAC6 inhibitors. In particular, the α-methyl-substituted enantiomer I (3-S) showed significant in-cell tubulin acetylation (Tub-Ac) with an EC₅₀ of 0.30 μM but limited impact on p21 levels at various concentrations In enzyme inhibition assays, I demonstrated high selectivity for HDAC6 with an IC₅₀ of 0.017 μM and selectivity indexes of 10 against HDAC8 and over 4000 against HDAC1-3 isoforms. Moreover, I has suitable drug metabolism and pharmacokinetics properties compared with other hydroxamic acid-based HDAC inhibitors, warranting further biol. studies and development as a selective HDAC6 inhibitor.

Weng, Qinjie published the artcilePhenotypic Screening-Based Identification of 3,4-Disubstituted Piperidine Derivatives as Macrophage M2 Polarization Modulators: An Opportunity for Treating Multiple Sclerosis, Application of Methyl 4-bromo-3-chlorobenzoate, the publication is Journal of Medicinal Chemistry (2019), 62(7), 3268-3285, database is CAplus and MEDLINE.

Multiple sclerosis (MS) is a disease of the autoimmune-mediated disorder in the central nervous system, for which no effective therapeutic agent is currently available. The regulation of macrophage polarization toward M2 is a general benefit for treating MS. The gene biomarker-based phenotypic screening approach was developed, and 3,4-disubstituted piperidine derivative S-28 was identified as a lead compound modulating macrophage M2 polarization. Further SAR studies resulted in the discovery of the most potent modulator D11 that showed good oral bioavailability and significant in vivo therapeutic effects. Mechanistic studies demonstrated that the M2 polarization macrophages modulated by D11 mainly functioned through inhibiting the proliferation of T-cells and activating the phosphorylation of Stat3 and Akt. Therefore, the gene biomarker-based phenotypic screening was demonstrated as a promising tool for the discovery of novel macrophage M2 polarization modulators. Compound D11 may serve as a promising starting point for the development of therapeutics to treat MS.
