1,3,5-triazine-2,4,6-triamine compound or pharmaceutical acceptable salt thereof, and pharmaceutical composition comprising the same

Polyamine compounds, method of synthesis and method of use for anti-cancer purposes, for enhancing the activity of existing anti-cancer drugs, as well as, for inhibiting N-Methyl-D-Aspartate (NMDA) receptors found in neurotransmission systems are provided. Certain polyamine motifs have been identified that can be attached to toxic agents to facilitate their access to cancer cells as well as polyamine compounds of surprising cytotoxicity with selectivity in killing cancer cells, and surprising utility in the treatment of Alzheimer's disease and brain stroke. It includes an illustrative conjugate system with examples of a triamine or a tetraamine appended to a cytotoxic agent. Included is a general strategy to enhance cell uptake by attaching a polyamine vectoring system with an example of a triamine vector attached to an existing anti-cancer drug to improve its chemotherapeutic potency. There is an illustration of tetraamine derivatives which have surprising enhanced selectivity in inhibiting N-methyl-D-aspartate (NMDA) receptors involved in neurotransmission. Several ligands can affect the activity of this receptor, which has been shown to initiate cell death under stroke conditions (lack of oxygen). Tetraamine derivatives which bind or inhibit the action of the NMDA receptor provide new therapy for NMDA-associated human diseases, such as Alzheimer's disease and stroke.

Polyamine conjugates as selective NMDA inhibitors and anti-cancer drugs

Polyamine compounds, method of synthesis and method of use for anti-cancer purposes, and for enhancing the activity of existing anti-cancer drugs are provided. This disclosure has identified certain polyamine motifs that can be attached to toxic agents to facilitate their access to cancer cells as well as polyamine compounds of surprising cytotoxicity and selectivity in killing cancer cells. It includes an illustrative conjugate system with examples of a triamine or a tetraamine appended to a cytotoxic agent. There are five method schemes illustrative of the synthesis of the compounds of the invention. Included is a general strategy to enhance cell uptake by attaching a polyamine vectoring system with an example of a triamine vector attached to an existing anti-cancer drug to improve its chemotherapeutic potency. There is an illustration of using the triamine vector to improve the selectivity of an anthracenylmethyl amine cytotoxic agent (e.g. an anthracenylmethyl-4,4-triamine conjugate outperformed an anthracenylmethyl N-butyl amine derivative). There is an illustration of a synthetic method to attach the polyamine vector onto an existing chemotherapeutic, doxorubicin. This methodology can lead to the synthesis of the polyamine-doxorubicin conjugate. There are illustrations of the synthesis of various alkyl aryl substituted polyamines, a hydroxylated polyamine derivative and a cyclohexyldiamine analogue.

Compounds and method for enhancing the efficacy of anti-cancer drugs

Novel tri(platinum) complexes containing three platinum coordination spheres coupled via diamine or triamine bridging agents are taught as well as methods for their preparation. These complexes are to be used as pharmaceutical agents, e.g., for the treatment of cancer and parasitic diseases.
