Abstract

The aim of this study is to evaluate the effect of moderate physical exercise and treatment time on the organism's response to NSC631570. The sensitivity of circulating phagocytes to the drug at different times of day was estimated in in vitro experiments. NSC631570 was administered intravenously to healthy volunteers (eleven men, 23±2 years) in a single therapeutic dose in an inpatient and an outpatient setting. Blood samples were obtained before the drug administration, 30min after the drug injection and every fourth hour throughout the 24 hour period. Biochemical parameters were determined using the hematological analyzer. Flow cytometry was used to evaluate phagocyte metabolism. Treatment of circulating phagocytes with NSC631570 in vitro resulted in an increase in ROS production along with a decrease in their phagocytic activity, most expressed in the morning time. Drug injection to sedentary persons resulted in pro-inflammatory metabolic polarization of circulating phagocytes. Introduction of NSC631570 to active persons was accompanied by a significant increase in phagocyte endocytosis along with a decrease in the daily mean of ROS generation. Significant oscillation (but in the normal ranges) of urea, creatinine, alanine aminotransferase and aspartate aminotransferase after NSC631570 introduction in the outpatient setting was shown during the day. Physical activity interferes with immunomodulatory action of NSC631570 and abrogates pro-inflammatory shift of circulating phagocytes. Biochemical parameters of blood from patients treated with NSC631570 in the outpatient setting must be interpreted cautiously considering the effect of physical activity on some metabolic biomarkers.
