项目摘要
Abstract
Preclinical, clinical and epidemiological studies provide compelling evidence that
nonsteroidal anti-inflammatory drugs (NSAIDs) have antineoplastic activity and significantly
reduce the incidence and risk of death from multiple cancer types, including lung cancer.
Unfortunately, the long-term use of NSAIDs for chemoprevention and their potential application
for therapy are not recommended because of the risk of potentially fatal side-effects resulting
from cyclooxygenase (COX) inhibition and the suppression of physiologically important
prostaglandins. However, numerous investigators have concluded that the pharmacological
basis for their antineoplastic activity may not require COX inhibition, which suggests the
feasibility of developing safer and more efficacious non-COX inhibitory derivatives for cancer by
targeting the underlying mechanism. We have extensively studied the mechanism by which the
NSAID, sulindac inhibits tumor cell growth and have reported that this activity results from cyclic
guanosine monophosphate phosphodiesterase (cGMP PDE) inhibition and the activation of
cGMP/protein kinase G signaling to suppress oncogenic β-catenin/Tcf-transcriptional activity
and the synthesis of key proteins, such as cyclin D1 and survivin that drive tumor cell
proliferation and survival. Here we show that the cGMP degrading PDE isozyme, PDE10A is a
critically important target of sulindac that is elevated in lung tumors and essential for lung tumor
cell growth. Guided by molecular modeling using the crystal structure of PDE10, we synthesized
a novel series of sulindac derivatives that potently and selectively inhibit lung tumor cell growth
without inhibiting COX-1 or COX-2. These compounds have attractive drug-like properties
whereby high lung concentrations relative to plasma and other tissues can be safely achieved
by oral administration. A lead compound, MCI-048 was identified that displays strong antitumor
activity in an orthotopic mouse model of lung cancer. Further analog development to identify a
preclinical drug development candidate and studies to better define the role of PDE10 in lung
cancer are therefore urgently needed. The following aims are proposed: 1) synthesize a novel
series of sulindac derivatives to improve potency and selectivity, 2) evaluate PDE10 and lung
tumor cell growth inhibitory activity of sulindac derivatives, 3) evaluate antitumor activity of
sulindac derivatives in mouse models of lung cancer, and 4) further define the role of PDE10 in
lung cancer. The focus of this project on the development of novel anticancer drugs and target
validation for chemoprevention or therapy have the potential to impact individuals at risk of
developing lung cancer as well as patients with advanced stage malignant disease.
摘要
临床前、临床和流行病学研究提供了令人信服的证据,
非甾体抗炎药(NSAID)具有抗炎活性,
降低多种癌症类型(包括肺癌)的发病率和死亡风险。
不幸的是,长期使用非甾体抗炎药的化学预防和他们的潜在应用,
不推荐使用,因为可能会导致致命的副作用
从环氧合酶(考克斯)抑制和生理上重要的
兰丁然而,许多研究人员得出结论,
