Computer-aided Evaluation of Polyvalent Medications' Pharmacological Potential. Multiphytoadaptogen as a Case Study.

Many human diseases including cancer, degenerative and autoimmune disorders, diabetes and others are multifactorial. Pharmaceutical agents acting on a single target do not provide their efficient curation. Multitargeted drugs exhibiting pleiotropic pharmacological effects have certain advantages due to the normalization of the complex pathological processes of different etiology. Extracts of medicinal plants (EMP) containing multiple phytocomponents are widely used in traditional medicines for multifactorial disorders' treatment. Experimental studies of pharmacological potential for multicomponent compositions are quite expensive and time-consuming. In silico evaluation of EMP the pharmacological potential may provide the basis for selecting the most promising directions of testing and for identifying potential additive/synergistic effects. Multiphytoadaptogen (MPhA) containing 70 major phytocomponents of different chemical classes from 40 medicinal plant extracts has been studied in vitro, in vivo and in clinical researches. Antiproliferative and anti-tumor activities have been shown against some tumors as well as evidence-based therapeutic effects against age-related pathologies. In addition, the neuroprotective, antioxidant, antimutagenic, radioprotective, and immunomodulatory effects of MPhA were confirmed. Analysis of the PASS profiles of the biological activity of MPhA phytocomponents showed that most of the predicted anti-tumor and anti-metastatic effects were consistent with the results of laboratory and clinical studies. Antimutagenic, immunomodulatory, radioprotective, neuroprotective and anti-Parkinsonian effects were also predicted for most of the phytocomponents. Effects associated with positive effects on the male and female reproductive systems have been identified too. Thus, PASS and PharmaExpert can be used to evaluate the pharmacological potential of complex pharmaceutical compositions containing natural products.

Integrins LFA-1 and Mac-1 and cytokines IL-6 and IL-10 in high-cancer mice under the influence of phytoadaptogen.

The expression of leukocyte integrins LFA-1 and Mac-1 and cytokines IL-6 and IL-10 was studied in mice predisposed to spontaneous hepatocarcinomas. The efficacy of a phytoadaptogen in correcting these parameters was evaluated. The role of adhesive interactions between immune cells and target cells in the recovery of antitumor regulatory mechanisms was estimated.

[Investigation of multyphytoadaptogene anti-radiation activity in mice].

The aim of the work was to elucidate the radioprotective activity of multyphytoadaptogene (MPA) in mice in various conditions of gamma radiation and MPA application. Males of CBA x C57BL/6 F1 mice were given 15% MPA solution with drinking water 2 weeks before the radiating (preventive application), 2 weeks before and 2 weeks after the radiating (preventive and therapeutic application) and also 2 weeks after the radiating only (therapeutic application). Animals of control groups received radiation or were given 5% ethanol solution in drinking water in the same application schemes. MPA increased the mice survival in preventive, preventive and therapeutic as well as therapeutic applications after 7.5 Gy radiation (66.7: 66.4 and 40.2% correspondingly). After 11.0 Gy radiation MPA increased the mice survival in preventive as well as preventive and therapeutic applications (75.0 and 76.9% correspondingly). MPA administration improved the somatic state, weight of animals, quality of life. MPA has no side effects. The data suggest the radioprotective activity of MPA.

[Antimutagenesis of multiphytoadaptogene in yeast saccharomyces].

Multiphytoadaptogene (MPA) consists of plant extracts components including adaptogenes. Genotoxicity analysis revealed the antimutagenic activity of MPA. MPA decreased the direct mutations frequency in ADE4-ADE8 loci induced by UV radiation and nitrous acid by 3.7 and 33 times, respectively. The lethal effect of UV radiation was inhibited when the preparation was used. MPA had no effect on replicative mutagenesis. At the same time it depressed mutagenesis caused by repair errors. The data obtained suggest the antimutagenic activity of multiphytoadaptogene is associated with postreplicative repair activation.

[Investigation of multyphytoadaptogene anti-radiation efficacy in dogs experiments].

The purpose of the work was to elucidate the radioprotective efficacy of multyphytoadaptogene (MPA) in dogs in various conditions of gamma radiation and MPA application. Dogs were given 15% MPA solution with drinking water in 3,6 ml/kg dose per day 2 weeks before the radiating (preventive application), 2 weeks before and 2 weeks after the radiating (preventive and therapeutic application) as well as 2 weeks after the radiating only (therapeutic application). Animals of control groups received radiation. Dogs were exposed to 3,5 Cy acute radiation and 8,0 Gy prolonged radiation. There were no survived dogs in control groups. At the same time MPA increased dogs survival in preventive, preventive and therapeutic as well as therapeutic applications after 3,5 Gy acute radiation and after 8,0 Gy prolonged radiation. MPA improved the somatic state, interfere with leukocytes amount in blood. The data obtained suggest the radioprotective efficacy of MPA.
