Potential use in terms of cancer.Simultaneously as DNA damage repair mechanism be tumor cell reply chemotherapeutics and
Ionizing radiation treatment produces resistance to main mechanism the affected, and therefore PARP-1 is considered as to explore new cancer to control
One Effective target site for the treatment of method.
The PARP inhibitor of early development design is the nicotiamide work using the NAD as PARP catalytic substrate
For template, develop its analog.These inhibitor, as the competitive inhibitor of NAD, are competed with NAD
The catalytic site of PARP, and then stop the synthesis of poly-(ADP-ribose) chain.There is no poly-(ADP-ribosyl
Change) modify lower PARP and cannot disintegrate down from DNA damage site, other will be caused to participate in the egg of reparations
White matter cannot be introduced into injury site, and then can not perform repair process.Therefore, in cytotoxic drug or radiation
Effect under, the tumor cell that the existence of PARP inhibitor makes DNA impaired is the most dead.
Additionally, the NAD being consumed as PARP catalytic substrate, it is must not during cell synthesizes ATP
Can lack, therefore, under high PARP activity level, intracellular NAD level can be remarkably decreased, and then
Affect the ATP level of intracellular.Owing to intracellular ATP content is not enough, cell cannot realize what ATP relied on
Programmed cell death process, can only turn to this special apoptotic process downright bad.During necrosis, substantial amounts of inflammation
Inflammation factor can be released, thus other organs and tissue are produced toxic action.Therefore, PARP suppression
Agent can be used for treating the multiple disease relevant with this mechanism, including neurodegenerative diseases (as old age is crazy about
Slow-witted disease, Huntington chorea, parkinson disease), diabetes, the concurrent disease in ischemia or Ischemia-Reperfusion Injury
Disease, such as myocardial infarction and acute renal failure, blood circulation diseases, such as septic shock, and diseases associated with inflammation,
Such as chronic rheumatism etc..
