Uses

(+/-)-SLV 319 is a mixture of the CB1 antagonist SLV 319 and its distomer.

Biological Activity

slv 319 is described here instead of (±)-slv 319. slv 319, also called ibipinabant, is a cb1 antagonist with an ic50 value of 22 nm [1, 2].there are 2 types of cannabinoid receptors (cb1 and cb2). their endogenous ligands are primarily anandamide and 2-ag. cannabinoid receptors and their endogenous ligands together are prominent in the control of food intake and energy metabolism. stimulation of this endocannabinoid system triggers metabolic processes and leads to lipogenesis, weight gain, insulin resistance, dyslipidemias and impaired glucose homeostasis [2].c2c12 murine myoblasts were model cells. exposure to increasing concentrations of ibipinabant at the highest concentration tested (100 μm) for 24 hours significantly decreased cell viability to 73 ± 5%. after 48 hours of exposure to the drug at this concentration only 33 ± 4% of cells remained viable. cellular reactive oxygen species (ros) generation is an index of mitochondrial function. a more than 2-fold increase in cellular ros generation could already be observed after 8 hours exposure to ibipinabant at a concentration of 100 μm compared to the vehicle treated c2c12 myoblasts [3].cb1 receptor occupancy was related to potencies to increase dopamine (da) and norepinephrine (ne) releases. in the medial prefrontal cortex (mpfc), slv 319 caused a significant increase in the extracellular da level at 10 mg/kg. the time course of the effects of slv 319 and sr141716a at the 10-mg/kg dose appeared to be similar with peak effects at 30 and 180 min. but slv 319 showed a more pronounced biphasic effect on da release. slv319 administration caused significant increases in extracellular concentrations of 3,4-dihydroxyphenylacetic acid (dopac) and homovanillic acid (hva), metabolites of da and ne, after the 10-mg/kg dose in rat [4].

Check Digit Verification of cas no

The CAS Registry Mumber 362519-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,6,2,5,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 362519-49:
(8*3)+(7*6)+(6*2)+(5*5)+(4*1)+(3*9)+(2*4)+(1*9)=151
151 % 10 = 1
So 362519-49-1 is a valid CAS Registry Number.

An expedient atom-efficient synthesis of the cannabinoid CB1 receptor inverse agonist ibipinabant

Lange, Jos H.M.,Sanders, Hans J.,Van Rheenen, Jeroen

Page/Page column 10, (2010/04/03)

The invention relates to a novel chemical route to 3,4-diaryl-4,5-dihydro-(1H)-pyrazole-1-carboxamidine derivatives, known as potent cannabinoid-CB1 receptor antagonists, and to novel intermediates of these compounds. The synthetic route produced considerably higher yields than those reported, without the use of corrosive reagents. The process concerns the preparation of a compound of formula (I) wherein the symbols have the meanings given in the description.

Synthesis, Biological Properties, and Molecular Modeling Investigations of Novel 3,4-Diarylpyrazolines as Potent and Selective CB1 Cannabinoid Receptor Antagonists

J.,Ronken, Eric,Keizer, Hiskias G.,Tipker, Koos,McCreary, Andrew C.,Veerman, Willem,Wals, Henri C.,Stork, Bob,Verveer, Peter C.,Den Hartog, Arnold P.,De Jong, Natasja M. J.,Adolfs, Tiny J. P.,Hoogendoorn, Jan,Kruse, Chris G.

, p. 627 - 643 (2007/10/03)

A series of novel 3,4-diarylpyrazolines was synthesized and evaluated in cannabinoid (hCB1 and hCB2) receptor assays. The 3,4-diarylpyrazolines elicited potent in vitro CB1 antagonistic activities and in general exhibited high CB1 vs CB2 receptor subtype selectivities. Some key representatives showed potent pharmacological in vivo activities after oral dosing in both a CB agonist-induced blood pressure model and a CB agonist-induced hypothermia model. Chiral separation of racemic 67, followed by crystallization and an X-ray diffraction study, elucidated the absolute configuration of the eutomer 80 (SLV319) at its C4 position as 4S. Bioanalytical studies revealed a high CNS-plasma ratio for the development candidate 80. Molecular modeling studies showed a relatively close three-dimensional structural overlap between 80 and the known CB1 receptor antagonist rimonabant (SR141716A). Further analysis of the X-ray diffraction data of 80 revealed the presence of an intramolecular hydrogen bond that was confirmed by computational methods. Computational models and X-ray diffraction data indicated a different intramolecular hydrogen bonding pattern in the in vivo inactive compound 6. In addition, X-ray diffraction studies of 6 revealed a tighter intermolecular packing than 80, which also may contribute to its poorer absorption in vivo. Replacement of the amidine -NH2 moiety with a -NHCH3 group proved to be the key change for gaining oral biovailability in this series of compounds leading to the identification of 80.
