118509-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118509-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118509-98:
(8*1)+(7*1)+(6*8)+(5*5)+(4*0)+(3*9)+(2*9)+(1*8)=141
141 % 10 = 1
So 118509-98-1 is a valid CAS Registry Number.

4-Acyl Pyrrole Capped HDAC Inhibitors: A New Scaffold for Hybrid Inhibitors of BET Proteins and Histone Deacetylases as Antileukemia Drug Leads

Ahlert, Heinz,Bhatia, Sanil,Borkhardt, Arndt,Breit, Bernhard,Gunther, Stefan,Hansen, Finn K.,Hugle, Martin,Kraft, Fabian B.,Mishra, Pankaj,Schaker-Hubner, Linda,Schliehe-Diecks, Julian,Scholer, Andrea,Warstat, Robin

, p. 14620 - 14646 (2021/10/20)

Multitarget drugs are an emerging alternative to combination therapies. In three iterative cycles of design, synthesis, and biological evaluation, we developed a novel type of potent hybrid inhibitors of bromodomain, and extra-terminal (BET) proteins and histone deacetylases (HDACs) based on the BET inhibitor XD14 and well-established HDAC inhibitors. The most promising new hybrids, 49 and 61, displayed submicromolar inhibitory activity against HDAC1-3 and 6, and BRD4(1), and possess potent antileukemia activity. 49 induced apoptosis more effectively than the combination of ricolinostat and birabresib (1:1). The most balanced dual inhibitor, 61, induced significantly more apoptosis than the related control compounds 62 (no BRD4(1) affinity) and 63 (no HDAC inhibition) as well as the 1:1 combination of both. Additionally, 61 was well tolerated in an in vivo zebrafish toxicity model. Overall, our data suggest an advantage of dual HDAC/BET inhibitors over the combination of two single targeted compounds.

Cerium(IV)-induced nitration of cinnamic acids. Novel remote electrophilic substitution

Peterson, John R.,Do, Hoang D.,Dunham, Andrew J.

, p. 1670 - 1674 (2007/10/02)

The treatment of (E)-3,4-dimethoxycinnamic acid with ceric amonium nitrate in trifluoroacetic acid afforded (E)1,2-dimethoxy-4-nitro-5-(2-nitroethenyl)benzene in 79percent yield.The unusual ipso substitution of the carboxylic acid moiety by a nitro functional center illustrated a new reaction manifold of cerium(IV).Six cinnamic acids were examined to ascertain the generality of the transformation.The bidentate nitrato structure of the metal salt is believed to account for the nitrating ability of this system.
