项目摘要
Previously we designed and synthesized novel dual HDAC/PI3K inhibitors, identifying several novel molecules that inhibit both targets with single digit nanomolar potency. Selected compounds have been tested in the NCI60 cell line panel, showing anti-proliferation and cell-killing activity in several cell lines. A subset of these were examined in cell-based target engagement assays, confirming that the dual inhibitors engage both PI3K-delta and HDAC6 in cells. The lead compound (TRND00507679) induced necrosis in several mutant and FLT3-resistant AML cell lines and primary blasts from AML patients. We have developed the nano-particle formulation for TRND00507679 and TRND00421925 and studied their cellular uptake and anti-proliferative activity in several human cancer cell lines. TRND00507679 encapsulated nano-particles (TRND00507679-NPs) displayed a dose-dependent inhibition of tumor growth in an in vivo breast cancer Ehrlich ascites tumor (EAT) model. Additionally, we have also compared the tumor growth inhibition caused by PI3K-delta inhibitor, Idelalisib based nano-particles (Idelalisib-NPs) with that of TRND00507679-NPs. In contrast to Idelalisib-NPs, treatment of EAT tumors in mice was associated with substantial reduction in tumor growth by TRND00507679-NPs. The described work was published in the Journal of Medicinal Chemistry.
Current efforts have resulted in the publication of an international patent titled: Inhibitors of phosphoinositide 3-kinase and histone deacetylase for treatment of cancer. Additionally, filing of a joint inventorship patent between Hillstream Biopharma, Inc. and NCATS for these nano-formulated PI3K-delta/HDAC6 dual inhibitors was launched by recent submission of an Employee Invention Record (EIR) titled: Polymeric nanoparticles comprising a histone deacetylase 6/phosphoinositide 3-Kinase-delta dual inhibitor and related methods.
之前,我们设计并合成了新型双重HDAC/PI 3 K抑制剂,鉴定了几种新型分子,其以个位数纳摩尔效力抑制两种靶标。已在NCI 60细胞系组中测试了选定的化合物,在几种细胞系中显示出抗增殖和细胞杀伤活性。在基于细胞的靶标接合测定中检查了其中的一个子集,证实了双重抑制剂在细胞中接合PI 3 K-δ和HDAC 6。先导化合物(TRND 00507679)在几种突变型和FLT 3耐药AML细胞系和AML患者的原代母细胞中诱导坏死。我们已经开发了TRND 00507679和TRND 00421925的纳米颗粒制剂,并研究了它们在几种人类癌细胞系中的细胞摄取和抗增殖活性。TRND 00507679包封的纳米颗粒(TRND 00507679-NP)在体内乳腺癌埃利希腹水肿瘤(EAT)模型中显示出对肿瘤生长的剂量依赖性抑制。此外,我们还比较了由PI 3 K-δ抑制剂、基于Idelalisib的纳米颗粒(Idelalisib-NP)与TRND 00507679-NP引起的肿瘤生长抑制。 与Idelalisib-NP相反,小鼠中EAT肿瘤的治疗与TRND 00507679-NP显著降低肿瘤生长相关。所描述的工作发表在Journal of Medicinal Chemistry上。
目前的努力已经导致了一项国际专利的出版,该专利的名称为:用于治疗癌症的磷酸肌醇3-激酶和组蛋白脱乙酰酶的抑制剂。此外,Hillstream Bioburma,Inc.这些纳米配制的PI 3 K-δ/HDAC 6双重抑制剂的NCATS是通过最近提交的题为“包含组蛋白脱乙酰酶6/磷酸肌醇3-激酶-δ双重抑制剂的聚合物纳米颗粒和相关方法”的雇员发明记录(EIR)发起的。
