Potential Anti-Tumor Drug: Co-Crystal 5-Fluorouracil-nicotinamide.

5-Fluorouracil-nicotinamide (5-FU-NCM), a co-crystal with a 2D layer structure formed by hydrogen bonds, was synthesized by solvent evaporation and liquid phase-assisted grinding at room temperature. Compared to 5-FU alone, the results of solubility, oil-water partition coefficient, anti-tumor effect in vivo and vitro, acute toxicity, and pharmacokinetic parameters indicate that the co-crystal is a potential anti-tumor drug.

mer-Triaqua-(1,10-phenanthroline-κN,N')(sulfato-κO)magnesium(II).

In the title compound, [Mg(SO(4))(C(12)H(8)N(2))(H(2)O)(3)], the Mg(II) centre exhibits a slightly distorted octa-hedral coordination environment defined by two N atoms from a 1,10-phenanthroline mol-ecule, one O atom from a sulfate dianion and three meridionally arranged O atoms from coordinated water mol-ecules. The crystal structure involves intra- and intermolecular O-H⋯O hydrogen bonds.
