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.
提供聚胺化合物的合成方法和用于抗癌目的的使用方法,用于增强现有抗癌药物的活性,以及用于抑制神经递质系统中发现的N-甲基-D-天门冬氨酸(NMDA)受体。已经确定了某些聚胺基团,可以附加到毒性剂上,以促进它们进入癌细胞,以及具有惊人的细胞毒性选择性杀死癌细胞的聚胺化合物,并在阿尔茨海默病和脑卒中治疗方面具有惊人的实用价值。它包括一个具有三胺或四胺附加到细胞毒性剂的示例的说明性共轭系统。包括一般策略,通过附加聚胺矢量系统来增强细胞摄取,其中包括一个三胺矢量附加到现有抗癌药物上的示例,以提高其化疗效力。有一个四胺衍生物的示例,其在抑制神经递质中涉及的N-甲基-D-天门冬氨酸(NMDA)受体的选择性增强方面具有惊人的效果。几种配体可以影响该受体的活性,已经证明在缺氧的情况下引起细胞死亡。结合或抑制NMDA受体作用的四胺衍生物为NMDA相关的人类疾病提供了新的治疗方法,例如阿尔茨海默病和中风。
