AB  - It was reported that novel O,O′-diethyl-(S, S)-ethylenediamine-N,N′-di-2-(3-cyclohexyl) propanoate dihydrochloride (DE-EDCP) displayed in vitro antiproliferative activity on several human and mouse cancer cell lines, which was comparable to that of the prototypical anticancer drug cisplatin. In order to reveal its toxicity profile, acute and repeated-dose toxicity studies were performed in Naval Medical Research Institute (NMRI) Han mice. The intravenous LD 50 values of DE-EDCP were found to be 95.3 and 101.3 mg/kg body weight in female and male mice, respectively. In the subacute toxicity study, DE-EDCP was administered intravenously at the doses of 15, 25, and 40 mg/kg/day for a period of 28 days. There were no adverse effects on general condition, growth, feed and water consumption, and hematological parameters. There was a significant increase in urea and alanine aminotransferase in female mice and aspartate aminotransferase and alkaline phosphatase in both genders in 40 mg/kg/day dose-treated group. The histopathological changes confined to the liver and kidney, but in other organs were not found. Satellite group revealed that changes in the kidney and liver were less pronounced, suggesting their reversibility. Interactions with DNA could also be of importance for understanding DE-EDCP toxic side effects. Hyperchromic effect obtained with ultraviolet–visible, suggested electrostatic interactions between DE-EDCP and calf thymus DNA. The toxicity testing of DE-EDCP was conducted to predict human outcomes.

AB  - O,O'-diethyl-(S, S)-ethylenediamine-N, N'-di-2-(3-cyclohexyl) propanoate (DE-EDCP) is novel substance with cytotoxic activity in human leukemic cells. The aim of this study has been to predict in vivo bioavailability of the DE-EDCP and its potential metabolite (S, S)-ethylenediamine-N, N'-di-2-(3-cyclohexyl) propanoic acid (EDCP) by in vitro characterization which includes determination of lipophilicity and passive membrane permeability. There has also been evaluated inter-laboratory reproducibility of the bio-analytical method which was previously developed and validated for non-clinical study of the DE-EDCP and EDCP. Distribution coefficient n-octanol/water was 1.68 and 0.03, and apparent permeability coefficient was 4 x 10(-4) cm/s and 20 x 10(-4) cm/s, for the DE-EDCP and EDCP, respectively. Observed results have shown that the DE-EDCP is more lipophilic with better membrane retention, but the EDCP has better pass through the membrane. Also, there has been demonstrated a reproducibility and robustness of the proposed bio-analytical method.

AB  - A series of new (S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate esters has shown cytotoxic activity towards human leukemic cell lines. The aim of this study was to develop and validate a bioanalytical method for quantification of (S,S)-O,O-diethyl-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate dihydrochlorides (DE-EDCP) and its metabolite, substituted propanoic acid (EDCP), in mouse serum by ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Structural analog, derivative of 1,3-propanediamine, was used as an internal standard (IS). Sample preparation employed protein precipitation by acetonitrile and subsequent centrifugation. Optimal UHPLC separation conditions were set to achieve simultaneous determination of both compounds in a short run time of 6 min. Additionally, the selected reaction monitoring (SRM) mode developed in this method allowed a highly sensitive, accurate, and precise identification of compounds of interest. The lower limit of quantitation (LOQ) was 1.3 ng mL(-1) for DE-EDCP and 0.3 mu g mL(-1) for EDCP. The calibration curves were linear over the concentration range of 1.3-26.7 ng mL(-1) and 0.3-6.7 mu g mL(-1) for DE-EDCP and EDCP, respectively. Precision (%CV) and accuracy (% RE) for DE-EDCP and EDCP ranged from 3.5% to 16.0% and from 1.8% to 14.4%, respectively. The validation process was performed in accordance with the regulatory guidance/guideline, and all of the obtained results met the established acceptance criteria. The newly developed and validated UHPLC-MS/MS method is rapid, sensitive, and selective, and it can be successfully applied to drug monitoring in nonclinical studies.
