Aristolan, also known as aristolochic acid, is a group of naturally occurring chemicals found in the Aristolochia plant genus. These chemicals have been used in traditional medicine for centuries, particularly in Chinese and Ayurvedic practices, for their purported anti-inflammatory, antipyretic, and diuretic properties. However, recent studies have revealed that aristolochic acid is nephrotoxic and carcinogenic, causing severe kidney damage and increasing the risk of certain types of cancer, particularly upper urinary tract cancers. As a result, the use of Aristolochia-containing products has been banned or restricted in many countries due to their potential health risks.

3293-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3293-42-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,9 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3293-42:
(6*3)+(5*2)+(4*9)+(3*3)+(2*4)+(1*2)=83
83 % 10 = 3
So 3293-42-3 is a valid CAS Registry Number.

Sesquiterpene constituents from the liverwort Bazzania japonica

Lu, Runhua,Paul, Claudia,Basar, Simla,Koenig, Wilfried A.,Hashimoto, Toshihiro,Asakawa, Yoshinori

, p. 581 - 587 (2007/10/03)

The hydrodistillation products of the liverwort Bazzania japonica were separated by preparative gas chromatography (GC) and investigated by spectroscopic methods. Seven unknown compounds were isolated and identified by GC-MS and NMR. Four of them, the norsesquiterpene hydrocarbons 4-epi-11-nor-aristola-1(10),11-diene (1), 4-epi-11-nor-aristola-1,9,11-triene (2), 4-epi-11-nor-aristola-9,11-diene (3), and one oxygenated sesquiterpene, (-)-aristol-1(10)-en-12-ol (5) are new natural compounds, and one, (+)-himachala-2,4-diene (7), has for the first time been isolated from liverworts. The absolute configurations of 5 and 7 were derived by chemical correlation reactions and/or enantioselective GC using cyclodextrin phases. 1, 2 and 3 have identical absolute configuration.
