  • Publication number: 20210371441
    Abstract: A platinum complex comprises a chemical structure of Structure I: where L1 and L2 are independently selected from electron donor ligands, including but not limited to halogen ligands, hydroxo ligands, carboxylato ligands, and alkoxido ligands; R1, R2 and R3 are each independently selected from a hydrogen atom, hydrocarbon group, or heterocyclic group; wherein the hydrocarbon group is selected from: alkyl, alkenyl, cycloalkyl, phenyl, and naphthyl which may optionally be substituted by at least one functional group selected from the group consisting of: hydroxy, halogen, alkoxy, alkoxycarbonyl, carboxy, amido, amino, nitro, cyano, carbamate, urea, sulfonyl, sulfenyl, phosphenyl, phosphinyl, sulfide, thioether, thioester, sugar moiety, cyclodextrin, or porphyrin ring; and the heterocyclic group is selected from: pyridyl, piperidyl, azino, azolyl, imidazolyl, triazinyl, furyl or carbozolyl; or two adjacent R1, R2 and R3 groups form a heterocycle or a carbocycle with or without an intermediary hetero ato

  • Patent number: 10899781
    Abstract: A platinum complex includes a structure of Formula (I). A method for treating a subject suffering from cancer includes a step of administering an effective amount of the platinum complex to the subject. A method for inhibiting the growth of cancer cells includes the step of contacting a population of cancer cells with an effective amount of the platinum complex. The platinum complexes are particularly suitable for treatment of cancer through, in particular, photodynamic therapy.
