    • Several lines of evidence have shown a role for the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cGMP are not fully understood in the processing of pain in the spinal cord. cGMP-dependent protein kinase (PKG) Iα but not PKGIβ was localized in the neuronal bodies and processes, and was distributed primarily in the superficial laminae of the spinal cord. Intrathecal administration of an inhibitor of PKGIα, Rp-8-[(4-Chlorophenyl)thio]-cGMPS triethylamine, produces significant antinociception. Moreover, PKGIα protein expression was dramatically increased in the lumbar spinal cord after noxious stimulation. This upregulation of PKGIα expression was completely blocked not only by a neuronal NO synthase inhibitor, and a soluble guanylate cyclase inhibitor, but also by an N-methyl-D-aspartate (NMDA) receptor antagonist, MK-801. Noxious stimulation not only initially activates but also later upregulates PKGIα expression in the superficial laminae via an NMDA-No-cGMP signaling pathway, suggesting that PKGIα plays an important role in the central mechanism of inflammatory hyperalgesia in the spinal cord.
    • 一些证据表明,一氧化氮(NO)/环鸟嘌呤一磷酸(cGMP)信号通路在脊髓痛觉过敏发展中起作用。 然而,在治疗脊髓疼痛方面,cGMP的作用者的作用尚未完全了解。 cGMP依赖性蛋白激酶(PKG),而不是PKGIbeta位于神经元体内和过程中,主要分布于脊髓浅层。 PKGIalpha,Rp-8 - [(4-氯苯基)硫代] -cGMPS三乙胺的抑制剂的鞘内施用产生显着的抗感受伤害。 此外,PKGIalpha蛋白表达在有害刺激后在腰脊髓中急剧增加。 PKGIalpha表达的上调不仅被神经元NO合成酶抑制剂和可溶性鸟苷酸环化酶抑制剂,而且被N-甲基-D-天冬氨酸(NMDA)受体拮抗剂MK-801完全阻断。 有毒刺激不仅最初激活,而且后来通过NMDA-No-cGMP信号通路上调表达薄层中的PKGIalpha表达,表明PKGα在脊髓炎症性痛觉过敏的中枢机制中起重要作用。

    • Methods of treating tumors in a mammal, especially a human that has demonstrated resistance to other chemotherapeutic agents, is disclosed. Specifically, methods of the present invention are effective in tumors that have initially been unresponsive to taxane therapy, or have developed resistance during the course of treatment. The methods of the present invention comprise administering epothilone derivatives selected from those represented by the formula: The subject epothilone derivatives are advantageous in addition to their enhanced potency and effectiveness against tumors that have demonstrated resistance to therapy with taxane oncology agents in that they are efficacious upon oral administration.
