The paper presents the results of the research on the antitumor activity of a new drug - atomic clusters of silver (ACS), the colloidal solution of nanostructured silver bisilicate Ag6Si2O7 with particles size of 1-2 nm in deionized water. In vitro studies to evaluate the effect of various ACS concentrations in human tumor cells cultures (breast cancer, colon carcinoma and prostate cancer) were conducted. The highest antitumor activity of ACS was observed in dilutions from 2.7 mg/l to 5.1 mg/l, resulting in the death of tumor cells in all studied cell cultures. In vivo experiments on transplanted Ehrlich carcinoma model in mice consuming 0.75 mg/kg ACS with drinking water revealed significant inhibition of tumor growth since the 14th day of experiment (maximally by 52% on the 28th day, p < 0.05) in comparison with control. Subcutaneous injections of 2.5 mg/kg ACS inhibited Ehrlich's tumor growth on the 7th and 10th days of the experiment (p < 0.05) as compared to control.

Abstract The chemical composition, antitumor activity and toxicity of the essential oil from Lippia microphylla leaves (OEL) were investigated. The major constituents were thymol (46.5%), carvacrol (31.7%), p-cymene (9%), and γ-terpinene (2.9%). To evaluate the toxicity of OEL in non-tumor cells, the hemolytic assay with Swiss mice erythrocytes was performed. The concentration producing 50% hemolysis (HC50) was 300 μg/mL. Sarcoma 180 tumor growth was inhibited in vivo 38% at 50 mg/kg, and 60% at 100 mg/kg, whereas 5-FU at 50 mg/kg caused 86% inhibition. OEL displays moderate gastrointestinal and hematological toxicity along with causing some alteration in liver function and morphology. However, the changes were considered reversible and negligible in comparison to the effects of several anticancer drugs. In summary, OEL displays in vivo antitumor activity and a moderate toxicity, which suggests further pharmacological study.

 Objective: PITC-2 was isolated from the methanolic root extract of tissue cultured medicinal plant Pluchea indica (L.) Less. PITC-2 is a thiophene derivative which is 2-(Prop-1-ynyl)-5(5,6-dihydroxyhexa-1,3-diynyl)-thiophene. The main objective of the study is to evaluate the in vivo antitumor activity of PITC 2 against sarcoma-180 cancer cell in Swiss albino mice.Methods: The antitumor activity was evaluated by treatment with PITC-2 at a dose of 2.5 and 5 mg/kg b.w for 21 days on sarcoma-180 mice model. Cell viability was studied using 3-(4, 5- dimethylthiazol -2-yl)-2, 5-diphenyl tetrazolium bromide assay and cell apoptosis, G1 cell cycle arrest and reduction in tumor cell proliferation were evaluated by histopathological analysis and Bcl-2, cyclic-D1, and Ki-67 protein expression through immunohistochemistry study.Results: Precisely, PITC-2 had a cytotoxic effect on various in vitro cancer cells. Significant decreases in solid tumor volume and weight along with increase lifespan also observed. The histopathological and immunohistopathological examination indicates that PITC-2 induces apoptosis, typical morphological changes and suppresses tumor cell proliferation along with G1 cell cycle arrest through the downregulation of the intratumoral expression of Bcl-2, cyclic D1, and Ki-67 and thus highlighting antiproliferative and apoptotic properties against sarcoma-180 in vivo solid tumor model.Conclusion: The present results clearly demonstrate that PITC-2 significantly inhibits sarcoma-180 cell growth in a dose-dependent manner in in vivo mice model. Besides this, the study reveals a comprehensive perception of the possible mechanism behind the antitumor activity of PITC-2 by significant changes in the morphological, hematological, biochemical parameters in sarcoma-180 cells.

Antitumor activity of the adduct between Carboplatin and α-cyclodextrin has been tested against Sarcoma 180 (S180) and Ehrlich ascites carcinoma (EAC) murine tumors. The preliminary toxicity has also been evaluated by histological examinations of the treated animals. The results show the adduct has less antitumor efficacy than and similar toxicity to Carboplatin.

Significant variability of anticancer efficacy of dichloroacetate (DCA) stimulated an active search for the agents capable to enhance it antitumor action. Therefore, the aim of this work is the study of capability of aconitine-containing antiangiogenic agent BC1 to enhance anticancer activity of DCA against Ehrlich carcinoma. Materials and Methods: DCA (total dose was 1.3 g/kg of b.w.) and BC1 (total dose was 0.9 mg/kg of b.w.) were administered per os starting from the 2nd and 3rd days, respectively (8 admini strations for each agent). Antitumor efficacy of agents was estimated. Lactate level, LDH activity and the state of mitochondrial electron transport chain in tumor cells as well as phagocytic activity and reactive oxygen species (ROS) production of tumor-associated macrophages (TAM) were studied. Results: Combined administration of DCA and ВС1 resulted in 89.8% tumor growth inhibition (p < 0.001), what is by 22.5% (p < 0.05) higher that that of DCA alone. This combined treatment was accompanied with a decrease of lactate level in tumor tissue by 30% (p < 0.05) and significant elevation of LDH activity by 70% (p < 0.01). Increased level of NO-Fe-S clusters and 2-fold reduction of Fe-S cluster content were revealed in tumor tissue of mice after DCA and BC1 administration. It was shown that combined therapy did not effect TAM quantity and their phagocytic activity but stimulated ROS production by TAMs by 78% (p < 0.05) compared to this index in control animals. Conclusion: Antiangiogenic agent ВС1 in combination with DCA considerably enhances antitumor activity of DCA via significant decrease of Fe-S-containing protein level resulted from substantial elevation of nitrosylation of these proteins.
