Abstract In this article, three organotin complexes formulated as [(Me)2Sn(H2L1)] (1), [(Ph)2Sn(H2L1)]·MeOH (2) and [(Me)2Sn(HL2)(OAc)]4(Me)2O (3) (H4L1 = bis(2-hydroxybenzaldehyde) thiocarbohydrazone and H2L2 = bis(2-acetylpyrazine) thiocarbonohydrazone) have been synthesized and structurally characterized. Growth inhibition assays indicated that both the proligands and the three complexes are capable of showing anticancer activity against the human hepatocellular carcinoma HepG2 cells with H2L2 and complex 3 showing much higher cytotoxic potential. Subsequent toxicity studies on normal QSG7701cells showed that complex 3 has the highest tumor cell selectivity, and its IC50 value on QSG7701 cells is 8.48 fold higher than that in HepG2 cells. In acute toxicity experiments, complex 3 produces a dose-dependent effect in NIH mice with a LD50 value of 17.2 mg kg−1.

<b><i>Introduction:</i></b> Modulating specific biological effects through the changes in cytokine receptors’ expression level remains poorly understood. This study aimed to investigate the influence of the dose-dependent effect of TNF on the balance between proapoptotic and proliferation response depending on the parameters of TNFR1/2 expression density. <b><i>Methods:</i></b> Tumor cell lines (HEp-2, K-562, MCF-7, ZR-75/1, MOLT-4, IM-9, and Raji) were characterized for TNFR1/2 co-expression using flow cytometry and were studied to reveal the dose-dependent effect of rhTNF on cell cycle and apoptosis parameters. The associations among the studied parameters were estimated by correlation and regression analysis. <b><i>Results:</i></b> It was found for ZR-75/1 cells (the cell line characterized by high expression of both types) that a dose-dependent increase in expression of both types of TNF-α receptors on cells reduces the proliferative activity of cells. For MOLT-4 cells (which are characterized by lower expression), an increase in proliferative response of cells was positively associated with the percentage of both TNFR1<sup>+</sup> and TNFR2<sup>+</sup> cells. However, opposite effects on the cells were shown for the K-562 and MCF-7 lines having a similar expression profile. A similarity (a large percentage of double-positive cells) was revealed for the lines having similar effects (K-562 and ZR-75/1). <b><i>Conclusions:</i></b> High expression of TNF receptor type 1 is not always associated with predominant activation of proapoptotic pathways. However, in the case of simultaneous high expression of both types of receptors, the proportion of double-positive cells is crucial for the activation of either the proapoptotic or proliferation pathways.
