Check Digit Verification of cas no

The CAS Registry Mumber 63366-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,3,6 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63366-79:
(7*6)+(6*3)+(5*3)+(4*6)+(3*6)+(2*7)+(1*9)=140
140 % 10 = 0
So 63366-79-0 is a valid CAS Registry Number.

Structure-Based Drug Design of Mineralocorticoid Receptor Antagonists to Explore Oxosteroid Receptor Selectivity

Nordqvist, Anneli,O'Mahony, Gavin,Fridén-Saxin, Maria,Fredenwall, Marlene,Hogner, Anders,Granberg, Kenneth L.,Aagaard, Anna,B?ckstr?m, Stefan,Gunnarsson, Anders,Kaminski, Tim,Xue, Yafeng,Dellsén, Anita,Hansson, Eva,Hansson, Pia,Ivarsson, Ida,Karlsson, Ulla,Bamberg, Krister,Hermansson, Majlis,Georgsson, Jennie,Lindmark, Bo,Edman, Karl

The mineralocorticoid receptor (MR) is a nuclear hormone receptor involved in the regulation of body fluid and electrolyte homeostasis. In this study we explore selectivity triggers for a series of nonsteroidal MR antagonists to improve selectivity over other members of the oxosteroid receptor family. A biaryl sulfonamide compound was identified in a high-throughput screening (HTS) campaign. The compound bound to MR with pKi=6.6, but displayed poor selectivity over the glucocorticoid receptor (GR) and the progesterone receptor (PR). Following X-ray crystallography of MR in complex with the HTS hit, a compound library was designed that explored an induced-fit hypothesis that required movement of the Met852 side chain. An improvement in MR selectivity of 11- to 79-fold over PR and 23- to 234-fold over GR was obtained. Given the U-shaped binding conformation, macrocyclizations were explored, yielding a macrocycle that bound to MR with pKi=7.3. Two protein–ligand X-ray structures were determined, confirming the hypothesized binding mode for the designed compounds.

Isoxazole-Derived Amino Acids are Bromodomain-Binding Acetyl-Lysine Mimics: Incorporation into Histone H4 Peptides and Histone H3

A range of isoxazole-containing amino acids was synthesized that displaced acetyl-lysine-containing peptides from the BAZ2A, BRD4(1), and BRD9 bromodomains. Three of these amino acids were incorporated into a histone H4-mimicking peptide and their affinity for BRD4(1) was assessed. Affinities of the isoxazole-containing peptides are comparable to those of a hyperacetylated histone H4-mimicking cognate peptide, and demonstrated a dependence on the position at which the unnatural residue was incorporated. An isoxazole-based alkylating agent was developed to selectively alkylate cysteine residues in situ. Selective monoalkylation of a histone H4-mimicking peptide, containing a lysine to cysteine residue substitution (K12C), resulted in acetyl-lysine mimic incorporation, with high affinity for the BRD4 bromodomain. The same technology was used to alkylate a K18C mutant of histone H3.

A method for generating nitrile oxides from nitroalkanes: A microwave assisted route for isoxazoles

Giacomelli, Giampaolo,De Luca, Lidia,Porcheddu, Andrea

, p. 5437 - 5440 (2007/10/03)

A convenient route has been developed for generation of nitrile oxides in situ from nitroalkanes under very mild conditions using microwave irradiation, using 4-(4,6-dimethoxy[1,3,5]triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) and DMAP as catalyst.

Regioisomeric 3-, 4- and 5-aminomethyl isoxazoles: Synthesis and muscarinic activity

Dannhardt,Kiefer,Lambrecht,Laufer,Mutschler,Schweiger,Striegel

, p. 839 - 850 (2007/10/03)

A series of 3-, 4- and 5-aminomethyl isoxazoles and isoxazoles with one or two additional methyl groups at the heterocycle were synthesized in order to investigate the structural requirements, ie heterocyclic moiety, regiochemistry and length of an aminoalkyl unit, for muscarinic activity. This was assayed on isolated rabbit vas deferens (M1 receptor subtype) and isolated guinea-pig atrium (M2 receptor subtype) and ileum (M3 receptor subtype). The isoxazoles tested are one to three orders of magnitude less active than furane or oxadiazole derivatives, having similar structural characteristics except for the heterocycle. Thus, the differences in molecular point charges and charge distribution contribute to the muscarinic activity of these compounds more than small differences in molecular shape and conformational energies.

New N-aryl isoxazolecarboxamides and N-isoxazolylbenzamides as anticonvulsant agents

Lepage,Tombret,Cuvier,Marivain,Gillardin

, p. 581 - 593 (2007/10/02)

We prepared a series of N-aryl isoxazolecarboxamide, N-isoxazolylbenzamide compounds and derivatives and studied their anticonvulsant action in MES and MMS tests. Some of these reveal considerable activity, especially with respect to MES test. The disubstitution in the 2.6-position on the phenyl ring by two methyl groups would appear to be of primary importance for the activity. The amide bridge between the phenyl and isoxazolic rings, whether of the anilide or benzamide type, seems to show similar anticonvulsant behavior. We have selected the derivatives 8 (N-(2.6-dimethylphenyl)-5-methyl-3-isoxazolecarboxamide, 12 (N-(2.6-dimethylphenyl)-5-hydroxymethyl-3-isoxazolecarboxamide) and 51 (N-(5-methyl-3-isoxazolyl)-2.6-dimethylbenzamide) which are presently being studied in more extended pharmacological tests.
