Background: Carbazole-based molecules containing thiosemicarbazide functional groups are recognized for their diverse biological activities, particularly in enhancing therapeutic anticancer effects through inhibiting crucial pathways. These derivatives also exhibit noteworthy antioxidant properties.
Objectives: This study aims to synthesize, characterize, and evaluate the antioxidant and anticancer activities of 18 novel carbazole derivatives.
The hybrid molecules bearing heterocyclic structures in the A or D rings of steroids have significant biological activity. 16 ()-Hetereoarylidene steroids were synthesized from the reaction of different heteroaromatic carbaldehydes and -Dehydroepiandrosterone (DHEA) in a basic medium. Then, synthesis of the -formyl pyrazoline substituted new DHEA derivatives were carried out from the reaction of hydrazine hydrate and 16 ()-hetereoarylidene steroids.

The substance was given by subcutaneous injection at 20 mg/kg every other day for a total of 15 injections. At the end of the treatment, Se levels in serum were determined by fluorimetry, and those of vitamins A, E, C, and malondialdehyde in serum, liver, and kidney were determined by high-performance liquid chromatography.

We investigated the influence of 2-furan-2-yl-1H-benzimidazole regarding vitamins A, E, C, selenium (Se), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) levels on rats. 2-Furan-2-yl-1H-benzimidazole was given to rats by subcutaneous injection every other day for a total of 22 injections. At the end of the experiment, Se levels were determined by using a fluorimetric method.
