76778-33-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76778-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,7 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76778-33:
(7*7)+(6*6)+(5*7)+(4*7)+(3*8)+(2*3)+(1*3)=181
181 % 10 = 1
So 76778-33-1 is a valid CAS Registry Number.

Discovery of a new class of bicyclic substituted hydroxyphenylmethanones as 17β-hydroxysteroid dehydrogenase type 2 (17β-HSD2) inhibitors for the treatment of osteoporosis

Wetzel, Marie,Gargano, Emanuele M.,Hinsberger, Stefan,Marchais-Oberwinkler, Sandrine,Hartmann, Rolf W.

experimental part, p. 1 - 17 (2012/03/08)

E2 deficiency in elderly people has directly an effect on the skeleton and can lead to osteoporosis. As 17β-hydroxysteroid dehydrogenase type 2 (17β-HSD2) catalyses the conversion between active 17β-hydroxysteroid estradiol (E2) and testosterone (T) into their less active 17-ketosteroid and has been found in bones, 17β-HSD2 inhibitor may provide a new approach in the onset of osteoporosis. Bicyclic substituted hydroxyphenylmethanone derivatives were synthesised as steroidomimetics of the substrate E2 and were evaluated for their 17β-HSD2 inhibition and their selectivity toward 17β-HSD1, catalysing the reverse reaction the conversion of estrone (E1) into E2. Highly selective compounds (11, 12, 14, 21 and 22) have been identified, the most promising one (12) showing an IC50 value in the low nanomolar range (101 nM) and a selectivity factor of 13 toward 17β-HSD1. These results make compound 12 an interesting candidate for further biological evaluation.

Aryl 1,4-dialk(en)ylpiperazines as selective and very potent inhibitors of dopamine uptake

Van Der Zee,Koger,Gootjes,Hespe

, p. 363 - 370 (2007/10/02)

Substituted 1-[2-(diphenylmethoxy)ethyl]piperazines were synthesized and tested for inhibitory activity on dopamine uptake by synaptosomal preparations of rat corpus striatum. Especially 4-(3-phenyl-2-propenyl)substitution yielded very potent inhibitors with IC50 values of about 1 to 2 nM, activities that surpass that of benztropine 100 times. Compared with other monoamine uptake processes, the effect on dopamine uptake was highly specific. QSAR-analysis showed that substituents in the diphenylmethoxy group combining a strong inductive effect with a small volume provided optimal potency. In contrast, for those in the solitary phenyl group a combination of strong electron-withdrawing effect and a small volume was required.
