1. Sensitive enzyme immunoassay for the quantification of aclacinomycin A using beta-D-galactosidase as a label
M Sohda, K Fujiwara, H Saikusa, T Kitagawa, N Nakamura, K Hara, H Tone Cancer Chemother Pharmacol. 1985;14(1):53-8. doi: 10.1007/BF00552726.
A sensitive enzyme immunoassay method (EIA) for an anticancer drug, aclacinomycin A (ACM), has been developed. With a double-antibody technique, ACM at a concentration as low as 100 pg/tube can be detected. An antibody to ACM was obtained by immunizing rabbits with an antigen prepared by coupling ACM with mercaptosuccinylated bovine serum albumin via N-maleoyl aminobutyric acid (MABA) as a coupling agent. Enzyme labeling of ACM was performed with beta-D-galactosidase (beta-Gal; EC 3.2.1.23) via m-maleoyl benzoic acid (MBA). The standard curve of the assay was linear on a logit-log plot over a concentration range of 30 pg to 10 ng. The antibody detected ACM and its metabolites, MA144 M1 (M1), MA144 N1 (N1), MA144 S1 (S1), and aklavin (T1) equally well, but was only minimally reactive with aklavinone (D1) and 7-deoxyaklavinone (C1), thus suggesting that this EIA can detect the total amounts of ACM and its biologically active glycosides among metabolites of ACM. This EIA is practically free from interference by any other anticancer drugs. Using this assay, serum levels of ACM equivalents can be determined accurately after administration of the drug to rats at a single dose of 10 mg/kg. Since ACM is now undergoing clinical trial, the EIA of the drug will be a valuable tool in clinical pharmacological studies.
2. Biosynthesis of anthracycline antibiotics by Streptomyces galilaeus. I. Glycosidation of various anthracyclinones by an aclacinomycin-negative mutant and biosynthesis of aclacinomycins from aklavinone
T Oki, A Yoshimoto, Y Matsuzawa, T Takeuchi, H Umezawa J Antibiot (Tokyo). 1980 Nov;33(11):1331-40. doi: 10.7164/antibiotics.33.1331.
An aclacinomycin-negative mutant strain KE303 which required aklavinone aglycone for the production of anthracycline antibiotics was derived from Streptomyces galilaeus, and employed for the glycosidation of various anthracyclinones. epsilon- gamma- and beta-Rhodomycinones, epsilon-isorhodomycinone, epsilon- and beta-pyrromycinones and chemically modified aklavinones were found to be glycosidated to the biologically active anthracyclines, when they were fed to the growing culture. However, the feeding of daunomycinone, 13-deoxydaunomycinone, adriamycinone and steffimycinone did not yield any glycoside. The bioconversion of presumptive precursor glycosides revealed that aclacinomycin A is biosynthesized by the step-wise glycosidation from aklavinone vai aklavin and MA144 S1.
3. Radioimmunoassay for aclacinomycin A
Y Matsuzawa, T Kiyosaki, T Oki, T Takeuchi, H Umezawa Gan. 1982 Apr;73(2):229-33.
An antibody against aclacinomycin A (ACM) was produced in a rabbit by immunization with ACM-bovine serum albumin conjugate. The radioimmunoassay (RIA) was based on the competition of unlabeled anthracycline with 3H-labeled ACM for binding sites on a specific antibody. Antibody-bound and free antigen were separated by selective adsorption on dextran-coated charcoal. The antibody reacted equally with ACM and its metabolites, MA144 M1, MA144 S1 and aklavin, and could precisely distinguish aklavinone-related aglycones, adriamycin and daunomycin. RIA was sensitive in the range of 1 approximately 10 pmol per assay. The quantities of ACM and its metabolites in human plasma were practically determined without any pretreatment of physiological samples.
