133044-35-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133044-35-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,4 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133044-35:
(8*1)+(7*3)+(6*3)+(5*0)+(4*4)+(3*4)+(2*3)+(1*5)=86
86 % 10 = 6
So 133044-35-6 is a valid CAS Registry Number.

Synthesis and characterization of [3H]-SN56, a novel radioligand for the σ1 receptor

Fishback, James A.,Mesangeau, Christophe,Poupaert, Jacques H.,McCurdy, Christopher R.,Matsumoto, Rae R.

, p. 1 - 7 (2011)

The study of the binding characteristics of σ ligands in vivo and in vitro requires radiolabeled probes with high affinity and selectivity. The radioligand presently used for in vitro studies of the σ1 receptor, [3H](+)-pentazocine, has significant limitations; it is difficult to synthesize, has limited chemical stability, and can be problematic to obtain. Evaluation of a series of novel 2(3H)-benzothiazolone compounds revealed SN56 to have sub-nanomolar and preferential affinity for the σ1 subtype, relative to σ2 and non-sigma, binding sites. The goal of this study was to characterize the binding of [ 3H]-SN56 to σ1 receptors isolated from rat brain. Standard in vitro binding techniques were utilized to 1) determine the specificity and affinity of binding to σ1 receptors, 2) confirm that [3H]-SN56 labels sites previously identified as σ1 by comparing binding to sites labeled by [ 3H](+)-pentazocine, and 3) characterize the kinetics of binding. The results indicate that [3H]-SN56 exhibits 1) specific, saturable, and reversible binding to the σ1 receptor, with Bmax = 340 ± 10 fmol/mg and Kd = 0.069 ± 0.0074 nM, 2) competitive displacement by classical sigma compounds, yielding σ1 Ki values consistent with those reported in the literature, and 3) binding kinetics compatible with a 90 min incubation, and filtration for separation of free and bound radioligand. The results of these studies suggest that [3H]-SN56 may serve as a viable alternative to [3H](+)-pentazocine in radioligand binding assays.

Design and synthesis of 3-acyl-2(3H)-benzoxazolone and 3-acyl-2(3H)- benzothiazolone derivatives

Guenadil, Faouzi,Aichaoui, Hocine,Kapanda, Coco N.,Lambert, Didier M.,McCurdy, Christopher R.,Poupaert, Jacques H.

experimental part, p. 67 - 80 (2011/09/20)

A simpler and efficient "green" method using solid sodium hydroxide in a solvent mixture of acetone/water was found to catalyze N-acylation of 2(3H)-benzoxazolones and 2(3H)-benzothiazolones for facile and rapid synthesis of N-acyl derivatives in excellent yields. This method was applied to the synthesis of a series of 132 compounds employing a variety of acyl chlorides. Graphical abstract: [Figure not available: see fulltext.]

Study of the acylation reaction of 2(3H)-benzothiazolones in the mixture of ZnCl2-DMF

Guenadil, Faouzi,Aichaoui, Houcine

, p. 2633 - 2638 (2007/10/03)

The use of polyphosphoric acid and the complex AlCl3-DMF in 6-acylation of 2(3H)-benzothiazolones previously have been reported. Instead of the frequently used AlCl3 as a catalyst in the Friedl-Crafts reactions, we conducted the acyl
