Abstract
AbstractA new set of photoactivatable NADPH mimics bearing a thiourea linkage between a diarylbutadiene and an adenosine moiety functionalized by O-carboxymethyl groups has been designed and synthesized in a convergent strategy. These compounds display absorption and fluorescence emission maxima in DMSO (λmax,abs = 390 nm and λmax,em = 460 nm, respectively) consistent with the previously described analogues, with good fluorescence quantum yields (ΦF = 0.35–0.36), as well as two-photon absorption (σ2 = 10.1 GM at λmax,exc = 780 nm). These molecules could be useful photosensitive tools for biological studies, especially for cellular studies of nitric oxide synthases.
