Abstract
OBJECTIVE: Breast cancer is a global health concern, with millions of cases reported annually worldwide, making it the most common cancer among women. In India, the incidence of breast cancer has been steadily rising, reflecting a growing public health challenge and hence in the development of new drug moieties. Toxicity analysis of such novel drug candidates play a critical role in drug development, ensuring the safety and efficacy of potential therapeutics. Animal models, especially mice and zebrafish in the recent days, have been extensively used for toxicity evaluation owing to their physiological and genetic similarities to humans. This study was hence conducted with an aim to assess the toxicity using animal models, particularly mice and zebrafish. METHODS: In this study, 3-(2-(3,4-dimethoxyphenyl)-2-oxoethylidene)indolin-2-one (RAJI) - a chemically synthesised novel drug, was assessed for its toxicological potential in both zebrafish and mice models highlighting its survival, hatching, locomotor, neuromotor, behavioural abnormalities in zebrafish model and haematological and biochemical abnormalities in mice model. RESULTS: The results obtained emphasise that no significant damages were seen in both zebrafish (survival, hatching, locomotor, neuromotor, behavioural abnormalities) and mice (body weight, haematological and biochemical abnormalities) models when administered in low doses. CONCLUSION: All results obtained signifies that RAJI poses no harmful effects in the model organisms until administered in higher concentrations, thereby emphasising the fact that RAJI is a safe drug.
