Uses
Used in Pharmaceutical Industry:
7-METHYL CAMPTOTHECIN is used as an antitumor agent for its potential in cancer treatment. It functions as a DNA topoisomerase I inhibitor, which can help in the development of new camptothecin derivatives with improved efficacy and reduced side effects.
Used in Drug Design and Development:
7-METHYL CAMPTOTHECIN is used as a reference compound in the design and development of new camptothecin derivatives. Its properties and interactions with DNA topoisomerase I can provide valuable insights for creating more effective and targeted cancer treatments.
Used in QSAR Studies:
7-METHYL CAMPTOTHECIN is utilized in quantitative structure-activity relationship (QSAR) studies to understand the relationship between the chemical structure of camptothecin analogues and their biological activity as DNA topoisomerase I inhibitors. This information can be crucial for the development of more potent and selective anticancer drugs.
Check Digit Verification of cas no
The CAS Registry Mumber 78287-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,8 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78287-26:
(7*7)+(6*8)+(5*2)+(4*8)+(3*7)+(2*2)+(1*6)=170
170 % 10 = 0
So 78287-26-0 is a valid CAS Registry Number.

A radical substitution reaction of 20(S)-camptothecin (1) with methanol furnished 7-hydroxymethylcamptothecin (2). Reaction of 1 with primary alcohols higher than methanol gave 7-alkylcamptothecins (4), of which alkyl groups were one carbon less than the alcohols used and also 7-hydroxyalkylcamptothecins (5). For the preparation of 7-alkylcamptothecin (4), aldehydes were used as a radical source and several alkylated derivatives were synthesized. 7-Acyloxymethyl derivatives (6), 7-carbaldehyde (7), iminomethyl derivatives (10), acid (11), esters (12) and amides (13) were synthesized starting from 2. 7-Ethyl- (4b) and 7-propylcamptothecin (4c), acyloxymethyl compounds 6a, 6c and ethyl ester (12b) exhibited higher antitumor activity than 1 against L1210 in mice.
