In present investigation, self-assembled nanomicelles of amphiphilic clotrimazole glycyl-glycine (CLT-GG-SANMs) analogue were customized for augmenting drug delivery, permeability and apoptosis in B16F1 mouse melanoma cancer cells both in vitro and in vivo following intratumoral (i.t.:) route of administration. The mean particle size of CLT-GG-SANMs was measured to be 35.9 +/- 3.4 nm in addition to zeta-potential of -17.1 +/- 3.5 mV. The shape of CLT-GG-SANMs was visualized to be smooth and spherical as like nanoparticles. The critical micellar concentration (CMC) of CLT-GG-SANMs was estimated to be 17 mu g/ml using DPH (1,6-diphenyl-1,3,5-hexatriene) as a UV probe. Modification of CLT to CLT-GG-SANMs induced the amorphization in therapeutic moiety. Next, CLT suspension released only 9.7% of the drug within 1 h under dissolution testing and further analysis up to 48 h did not display any remarkable effect on the drug release. On the other hand, CLT-GG-SANMs released 46.2% of the drug significantly (P < 0.01) higher than CLT suspension at 4 h. The IC50 of CLT-GG-SANMs was measured to be 15.1-mu M significantly (P < 0.05) lower than CLT suspension (IC50 > 20 mu M) in B16F1 cells. Western blotting and histopathological analysis also supported the superior therapeutic efficacy of CLT-GG-SANMs in terms of higher extent of apoptosis, tumour regression and exhibition of strong antioxidant potential against B16F1 cells induced tumour in C57BL6J mice. In conclusion, in vitro and in vivo therapeutic efficacy analysis indicated that CLT-GG-SANMs may be a potential candidate for translating in to a clinically viable product.
