Description
Amrubicin is an active agent for the treatment of small-cell lung cancer (SCLC). It is a type of anthracycline analog. Anthracycline derivatives such as doxorubicin (DXR), daunorubicin (DNR) and epirubicin have been widely used for a variety of carcinomas in the clinical context. Amrubicin is structurally distinguishable from other anthracyclines by the amino group at the 9-position and its unique sugar moiety. In April 2002, Amrubicin was approved in Japan for the treatment of non-small cell lung cancer and small cell lung cancer.
Uses
Synthetic anthracycline antibiotic; inhibits DNA topoisomerase II. Antineoplastic. Amrubicin is used to treat small-cell lung cancer (SCLC).
Definition
ChEBI: Amrubicin is a synthetic anthracycline antibiotic with molecular formula C25H25NO9. A specific inhibitor of topoisomerase II, it is used (particularly as the hydrochloride salt) in the treatment of cancer, especially lung cancer, where it is a prodrug for the active metabolite, ambrucinol. It has a role as a topoisomerase II inhibitor, an antineoplastic agent and a prodrug. It is a quinone, a member of tetracenes, a methyl ketone, an anthracycline antibiotic and a primary amino compound.
Mode of action
Amrubicin (AMR), a third-generation anthracycline and potent topoisomerase II inhibitor that intercalates into DNA and inhibits the activity of topoisomerase II, resulting in inhibition of DNA replication, and RNA and protein synthesis, followed by cell growth inhibition and cell death. Amrubicin is structurally distinguishable from other anthracyclines by the amino group at the 9-position and its unique sugar moiety. This agent has demonstrated a higher level of anti-tumor activity than conventional anthracycline drugs without exhibiting any indication of the cumulative cardiac toxicity common to this class of compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 110267-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,2,6 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 110267-81:
(8*1)+(7*1)+(6*0)+(5*2)+(4*6)+(3*7)+(2*8)+(1*1)=87
87 % 10 = 7
So 110267-81-7 is a valid CAS Registry Number.

A method for synthesizing ammonia supple ratio star

, (2017/02/24)
The invention discloses a synthetic method for amrubicin. R-2-acetyl-2-acetamido-5,8-dimethoxy-1,2,3,4-tetrahydronaphthalene is used as a raw material, and is subjected to acylation and cyclization with phthalic anhydride. 1,3-propanediol and derivatives thereof are used to protect carbonyl, and the protective group is liable to remove in a hydrolysis reaction. The amrubicin is prepared by a step of subjecting (+)-9-amino-4-demethoxy-9-deoxy-daunomycinone with 2-deoxy-3,4-di-O-acetyl-beta-D-erythro-pentapyranosyl-1,1,1-trichloroiminoacetate to a nucleoside-forming reaction to obtain (+)-9-amino-4-demethoxy-9-deoxy-7-O-(2-deoxy-3,4-di-O-acteyl-beta-D-erythro-pentapyranosyl) daunomycinone, and a step of removing acetyl. The synthetic method can avoid generation of isomers during a hydrolysis process effectively. The synthetic method has simple subsequent purification steps. The nucleoside-forming reaction can decrease the production cost effectively. The synthetic method is suitable for industrial applications.
