[The inhibitory effect of the synthetic leu-enkephalin analog dalargin on carcinogenesis]. 1990

V N Anisimov, and S M Bortkevich

Dalargin, an opioid peptide (Tyr-D-Ala-Gly-Phe-Leu-Arg), was shown to significantly inhibit the carcinogenic effect of 50 mg/kg body weight nitrosomethylurea given as single i. v. infection. The treatment was followed by an increase in the tumor latency period. Moreover, the overall incidence of tumors decreased by 20% whereas that of malignant neoplasms and breast adenocarcinoma--by 33 and 27%, respectively. Pronounced inhibitory effect of dalargin on hematopoietic tumor induction was identified, too.

D013565	Sympatholytics	Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see ADRENERGIC AGENTS). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see ADRENERGIC ALPHA-AGONISTS) are included here.
