Drug Delivery with a Calixpyrrole–trans-Pt(II) Complex
摘要:
A meso-p-nitroaniline-calix[4]pyrrole derivative trans-coordinated to a Pt(II) center was synthesized and its structure solved by X-ray analysis. Adenosine monophosphate (AMP) was used as a model compound to evaluate the potential for the assisted delivery of the metal to the DNA nucleobases via the phosphate anion-binding properties of the calix[4]pyrrole unit. An NMR investigation of the kinetics of AMP complexation in the absence of an H-bonding competing solvent (dry CD3CN) was consistent with this hypothesis, but we could not detect the interaction of the calix[4]pyrrole with phosphate in the presence of water. However, in vitro tests of the new trans-calixpyrrole- Pt(II) complex on different cancer cell lines indicate a cytotoxic activity that is unquestionably derived from the coexistence of both the trans-Pt(II) fragment and the calix[4]pyrrole unit.

synthetic protocols for the synthesis of diverse dipyrromethanes (DPMs) and calix[4]pyrroles (C4Ps), there is a supreme need to synthesize these valued supramolecular receptors under green conditions. Therefore, herein we report for the first time, a simple yet very effective green protocol for the construction of diverse functionalized DPMs and C4Ps in respectable yields without the involvement of an additional
