40891-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40891-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,9 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40891-33:
(7*4)+(6*0)+(5*8)+(4*9)+(3*1)+(2*3)+(1*3)=116
116 % 10 = 6
So 40891-33-6 is a valid CAS Registry Number.

Synthesis of dipyrrolo[2,3-a:1′,2′,3′-fg]acridin-12(1H)-ones

Acylation reactions of 4,6-dimethoxyindoles with glyoxyloyl chlorides were achieved by the use of graphite powder in 1,2-dichloroethane at reflux. The products were monoketones as a result of decarbonylation, rather than the expected 1,2-diketones. Treatment of these monoketones with base led to their cyclisation and elimination of methanol to afford the novel dipyrrolo[2.3-a:1′,2′,3′-fg]acridin-12(1H)-ones.

The discovery of a potential ligand-targeting G protein-coupled receptor 17 (GPR17) is important for developing chemotherapeutic agents against glioblastoma multiforme (GBM). We used the integration of ligand- and structure-based cheminformatics and exper

Discovery of Novel Dual-Target Inhibitor of Bromodomain-Containing Protein 4/Casein Kinase 2 Inducing Apoptosis and Autophagy-Associated Cell Death for Triple-Negative Breast Cancer Therapy

Bromodomain-containing protein 4 (BRD4) is an attractive epigenetic target in human cancers. Inhibiting the phosphorylation of BRD4 by casein kinase 2 (CK2) is a potential strategy to overcome drug resistance in cancer therapy. The present study describes the synthesis of multiple BRD4–CK2 dual inhibitors based on rational drug design, structure–activity relationship, and in vitro and in vivo evaluations, and 44e was identified to possess potent and balanced activities against BRD4 (IC50 = 180 nM) and CK2 (IC50 = 230 nM). In vitro experiments show that 44e could inhibit the proliferation and induce apoptosis and autophagy-associated cell death of MDA-MB-231 and MDA-MB-468 cells. In two in vivo xenograft mouse models, 44e displays potent anticancer activity without obvious toxicities. Taken together, we successfully synthesized the first highly effective BRD4–CK2 dual inhibitor, which is expected to be an attractive therapeutic strategy for triple-negative breast cancer (TNBC).

Design, synthesis and biological evaluation of novel HDAC inhibitors with improved pharmacokinetic profile in breast cancer

The dysfunction of histone deacetylase (HDACs) is closely related to tumorigenesis and development, which has been emerged as an attractive drug design target for cancer therapy. In the present study, we designed and synthesized a series of novel HDAC inhibitors using a substituted quinazoline as the capping group and attaching 3, 5-dimethylbenyl as a potential metabolic site protector. 23g and 23h were demonstrated potent HDAC inhibitory activities and anti-proliferative effects against MDA-MB-231 cells. In addition, 23g and 23h both could significantly increase the acetylation level of intracellular proteins, especially in α-Tubulin and HSP90. 23g and 23h displayed a slight different anti-tumor mechanism, 23g mainly induced apoptosis while 23h induced obviously ER-Stress. Furthermore, 23g and 23h both induced autophagy and migration inhibition. In pharmacokinetics assay, 23g showed a significant improvement of pharmacokinetic profile for oral administration. Additionally, 23g presented more potent anti-proliferation and anti-migration activity than SAHA in zebrafish MDA-MB-231 cell line-derived xenograft model. Together, these results demonstrate that 23g is a novel oral HDAC inhibitor with a potential capacity of treating breast cancer.
