RESEARCH AND DEVELOPMENT OF NEW DRUG PRODUCTS
The article presents information on the structure, classification and functions of NO-synthases. The main inhibitors of the enzyme, as well as their mechanisms of action, are considered. Among the substances activating the activity of the enzyme, special attention was paid to substances of nucleotide-peptide nature, using the example of a substance isolated from Saccharomyces cerevisiae race 14, it was found that the nucleotide preparation based on a substance isolated from Saccharomyces cerevisiae race 14. has a more pronounced activating action in comparison with T-activin, and helps to restore the functions of the enzyme in diseases such as diabetes.

ANALYTICAL METHODS
PRECLINICAL AND CLINICAL STUDIES
The aim of this work was to study the distribution of the labeled 123I peptide-protein drug Cellex in organs and tissues of rats after single intravenous injection and accumulation. After a single intravenous injection of radiolabeled [123I]Cellex it was found that the drug is characterized by rapid distribution into tissues and organs. The highest content of the drug in all organs and tissues was observed in 15 minutes after its administration. It was established that the drug penetrates the blood-brain barrier and about 6% of the drug accumulates in the brain, which is 10% of the total amount of the drug found in all organs in 15 minutes after administration.
