    Abstract: Photodynamic therapy (PDT) employing exogenous photosensitizers is currently being approved for treatment of basal cell carcinoma (BCC). 2-(4-Aminophenyl)benzothiazoles (6) consist of chromophoric structure and absorb light in the UVA (315-400 nm). These results encouraged us to design and synthesize a diversity of 2-phenylbenzothiazoles (6). Studies on the apoptotic mechanism involved in photosensitive effects induced by UVA-activated 6 in BCC cells are carried out in the present article. 6-UVA-treated cells displayed several features of apoptosis, including an increase in the sub-G1 population, a significantly increased annexin V binding, and activation of caspase-3. 6-UVA induced a decrease in mitochondrial membrane potential (Δψ<sub>mt</sub>) and ATP via enhanced ROS generation and promoted phosphorylation of extracellular signal-regulated kinase (ERK) and p38 MAPK expression. These results suggest that 6-UVA elicits photosensitive effects in mitochondria processes which involve ERK and p38 activation, and ultimately lead to BCC cell apoptosis.
