93673-09-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93673-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,7 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93673-09:
(7*9)+(6*3)+(5*6)+(4*7)+(3*3)+(2*0)+(1*9)=157
157 % 10 = 7
So 93673-09-7 is a valid CAS Registry Number.

4-(Benzoylindolizinyl)butyric acids; novel nonsteroidal inhibitors of steroid 5α-reductase. III

Sawada,Okada,Kuroda,Watanabe,Sawada,Tanaka

, p. 799 - 813 (2007/10/03)

A novel series of indolizinebutyric acids with various benzoyl substituents was synthesized to develop nonsteroidal inhibitors of steroid 5α-reductase, and the structure-activity relationships in this series were studied. We previously reported the structure-activity relationships in a series of indolebutyric acids as well as the discovery of the novel nonsteroidal 5α-reductase inhibitor, FK143. We have now made other modifications to this compound to improve in vivo inhibitory activity. By altering the heterocyclic nucleus and changing the benzoyl substituent we have succeeded in identifying the strongly active compound, FK687, (S)-4-[1-[4-[[1-(4-isobutylphenyl)butyl]oxy]benzoyl]indolizin-3-yllbutyric acid, which displays strong in vitro inhibitory activity against the human enzyme and in vivo inhibitory activity against the castrated young rat model. This compound should be a useful agent for the treatment of benign prostatic hyperplasia.

Preparation of (R)-Ibuprofen and Related Carboxylic Acids Using Microbial Oxidation of an Aromatic Hydrocarbon by Rhodococcus sp. BPM 1613

Sugai, Takeshi,Mori, Kenji

, p. 2501 - 2504 (2007/10/02)

(R)-2-(4'-Isobutylphenyl)propanoic acid (ibuprofen), (S)-3-(4'-isobutylphenyl)butanoic acid and (S)-4-(4'-isobutylphenyl)pentanoic acid were obtained using microbial oxidation of (+)-1-isobutyl-4-(1'-methyloctyl)benzene by Rhodococcus sp.BPM 1613.
