14994-81-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14994-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,9 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14994-81:
(7*1)+(6*4)+(5*9)+(4*9)+(3*4)+(2*8)+(1*1)=141
141 % 10 = 1
So 14994-81-1 is a valid CAS Registry Number.

Cycloaddition of: N -sulfonyl and N -sulfamoyl azides with alkynes in aqueous media for the selective synthesis of 1,2,3-triazoles

Prasanth, Thumpati,Chakraborti, Gargi,Mandal, Tirtha,Ravichandiran, Velayutham,Dash, Jyotirmayee

The cycloaddition of N-sulfonyl and N-sulfamoyl azides with terminal alkynes generally produces amide derivatives via ketenimine intermediates. We herein delineate a Cu(i) catalyzed method using a prolinamide ligand that selectively generates N-sulfonyl a

PYRIDINYL BASED APOPTOSIS SIGNAL-REGULATION KINASE INHIBITORS

-

Paragraph 0563; 0652, (2018/09/12)

Apoptosis signal-regulating kinase 1 (ASK1) activation and signaling have been reported to play an important role in a broad range of diseases including neurodegenerative, cardiovascular, inflammatory, autoimmunity and metabolic disorders. Disclosed herein is the synthesis of pyridinyl derived therapeutic agents that function as inhibitors of ASK 1 as well as their pharmaceutical compositions and methods of use.

Selective recognition of: C-MYC G-quadruplex DNA using prolinamide derivatives

Chauhan, Ajay,Paladhi, Sushovan,Debnath, Manish,Dash, Jyotirmayee

supporting information, p. 5761 - 5767 (2016/07/06)

Herein we report the design, synthesis, biophysical and biological evaluation of triazole containing prolinamide derivatives as selective c-MYC G-quadruplex binding ligands. A modular synthetic route has been devised for prolinamide derivatives using a copper(i) catalyzed azide-alkyne cycloaddition (CuAAC). The F?rster resonance energy transfer (FRET) melting assay indicates that prolinamide trimers can significantly stabilize G-quadruplex structures over duplex DNA compared to prolinamide dimers. The fluorescent intercalator displacement (FID) assay shows that a trimer with prolinamide side chains at the para-position of the benzene ring can discriminate between different quadruplex structures and exhibits the highest binding affinity towards the c-MYC G-quadruplex structure. Molecular modeling studies reveal that the prolinamide trimer stacks upon the terminal G-quartet of the c-MYC G-quadruplex. Atomic force microscopy (AFM) analysis reveals that the tris-prolinamide ligand can be used to regulate the assembly of novel supramolecular nanoarchitectures. Further, in vitro cellular studies with human hepatocellular carcinoma (HepG2) cells indicate that the tris-prolinamide derivatives can inhibit cell proliferation and reduce c-MYC expression in cancer cells.
