Check Digit Verification of cas no

The CAS Registry Mumber 84906-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,0 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84906-81:
(7*8)+(6*4)+(5*9)+(4*0)+(3*6)+(2*8)+(1*1)=160
160 % 10 = 0
So 84906-81-0 is a valid CAS Registry Number.

Quinoline carboxamide core moiety-based compounds inhibit P. falciparum falcipain-2: Design, synthesis and antimalarial efficacy studies

Singh, Anju,Kalamuddin, Md,Maqbool, Mudasir,Mohmmed, Asif,Malhotra, Pawan,Hoda, Nasimul

, (2020/12/07)

Targeting Falcipain-2 (FP2) for the development of antimalarials is a promising and established concept in antimalarial drug discovery and development. FP2, a member of papain-family cysteine protease of the malaria parasite Plasmodium falciparum holds an important role in hemoglobin degradation pathway. A new series of quinoline carboxamide-based compounds was designed, synthesized and evaluated for antimalarial activity. We integrated molecular hybridization strategy with in-silico drug design to develop FP2 inhibitors. In-vitro results of FP2 inhibition by Qs17, Qs18, Qs20 and Qs21 were found to be in low micromolar range with IC50 4.78, 7.37, 2.14 and 2.64 μM, respectively. Among the 25 synthesized compounds, four compounds showed significant antimalarial activities. These compounds also depicted morphological and food-vacuole abnormalities much better than that of E-64, an established FP2 inhibitor. Overall these aromatic substituted quinoline carboxamides can serve as promising leads for the development of novel antimalarial agents.

Discovery, synthesis and molecular substantiation of N-(benzo[d]thiazol-2-yl)-2-hydroxyquinoline-4-carboxamides as anticancer agents

Bindu,Vijayalakshmi,Manikandan

, (2019/08/07)

The effort was taken to develop a series of benzothiazole and quinoline fused bioactive compounds obtained through a four-step synthetic route using a range of substituted acetoacetanilides. Achieved N-(benzo[d]thiazol-2-yl)-2-hydroxyquinoline-4-carboxamides (6a-l) were produced up to 96% of yield while the eco-friendly p-TSA used as a catalyst. Further, the anticancer activity of these compounds was determined using a range of cancer cell lines starting from MCF-7 (Breast cancer), HCT-116 (Colon cancer), PC-3 & LNCaP (Prostate) and SK-HEP-1 (Liver cancer). Present study compounds were also testified for antioxidant properties prior to anticancer studies since the Reactive Oxygen Species (ROS) being vital in cancer development. To determine the cell membrane stability effects of the compounds, human red blood cells (HRBC) based membrane protection assay was determined. In the results, compounds 6a-l were able to produce a dominated result values over PC3 cell lines (Prostate cancer) than the other cell lines used in this study. Since the connectivity of human germ cell alkaline phosphatase (hGC-ALP) in the development of prostate cancer is known, the most active compounds were evaluated for the hGC-ALP inhibition in order to ensure a mechanism of anticancer action of these compounds. The mode of interaction and binding affinity of these compounds was also investigated by a molecular docking study. In the results, 6d, 6i, 6k, and 6l were found with least IC50 values 0.075 μM and highest relative activity of 92%, 90%, and 96% respectively. The need for further animal model evaluation and pre-clinical studies recognized.

, p. 2243 - 2250 (2007/10/03)

Microwave irradiation has been used for a rapid and efficient synthesis of quinoline-4-carboxylic acids 5a-g and 1,2,3,4-tetrahydroacridine-9-carboxylic acid (6) from the reaction of isatins 1-3 with acyclic and cyclic ketones in basic medium. 2-Hydroxyquinoline-4-carboxylic acid (11) was also obtained by irradiating a mixture of isatin 1 and malonic acid in AcOH. The esters of 5f and 11 and their respective hydrazides 8 and 13 were also prepared under MWI. Copyright Taylor & Francis, Inc.
