Biological activities of dithiocarbazate schiff base derivatives on normal and diabetic rats / Fathi Farag Mughrabi

The present study was performed to evaluate the acute toxicity, anti-ulcer, wound healing, antioxidant and antibacterial activities of a Schiff base namely benzyl N'-(indol-3-ylmethylidene)-hydrazinecarbodithioate (BIHC) and its metal complexes, BIHCZn and BIHCNi. The three compounds namely BIH...

Histological studies of the gastric wall of ulcer control group revealed severe damage of gastric mucosa, along with oedema and leucocytes infiltration of the submucosal layer compared to rats pre-treated with either BIHCD or Omeprazole where there were marked gastric protection along with the reduction or absence of oedema and leucocytes infiltration of the submucosal layer. BIHCD and its derivatives promote ulcer protection as ascertained by the comparative decreases in ulcer areas, reduction of oedema and leucocytes infiltration of the submucosal layer. Topical application of BIHC and its metal complexes on the wounds in normal and diabetic rats showed that wound dressed with BIHCD healed significantly earlier than those treated with 10% Tween 20.

Histological analysis of healed wound with BIHCD showed less scar width at wound enclosure and granulation tissue of healed wound contained comparatively less macrophages and large amount of collagen with angiogenesis compared to wounds dressed with 10% Tween 20. Based on the antioxidant activity studies, samples appear to contain low antioxidant properties compared to controls (Trolox, Retin, Ascorbic acid and Gallic acid). For the antibacterial activity, BIHCD appears to possess potential antibacterial activity against Staphylococcus aureus Pseudomonas aeruginosa, Klebsiella Phenumoniae but none against Streptococcus Group A.
