Synthesis and Biological Evaluation of Triazol-4-ylphenyl-Bearing Histone Deacetylase Inhibitors as Anticancer Agents
摘要:
Our triazole-based histone deacetylase inhibitor (HDACI), octanedioic acid hydroxyamide[3-(1-phenyl-1H-[1,2,3]triazol-4-yl)phenyl]amide (4a), suppresses pancreatic cancer cell growth in vitro with the lowest IC50 value of 20 nM against MiaPaca-2 cell. In this study, we continued our efforts to develop triazol-4-ylphenyl bearing hydroxamate analogues by embellishing the terminal phenyl ring of 4a with different substituents. The isoform inhibitory profile of these hydroxamate analogues was similar to those of 4a. All of these triazol-4-ylphenyl bearing hydroxamates are pan-HDACIs like SAHA. Moreover, compounds 4h and 11a were found to be very effective inhibitors of cancer cell growth in the HupT3 (IC50 = 50 nM) and MiaPaca-2 (IC50 = 40 nM) cancer cell lines, respectively. Compound 4a was found to reactivate the expression of CDK inhibitor proteins and to suppress pancreatic cancer cell growth in vivo. Taken together, these data further support the value of the triazol-4-ylphenyl bearing hydroxamates in identifying potential pancreatic cancer therapies.
N-alkyl-hydroxybenzoyl anilide hydroxamates as dual inhibitors of HDAC and HSP90, downregulating IFN-γ induced PD-L1 expression
摘要:
Novel dual inhibitors of histone deacetylase (HDAC) and heat-shock protein 90 (HSP90) are synthesized and evaluated. These compounds are endowed with potent HDAC and HSP90 inhibitory activities with IC50 values in nanomolar range with Compound 20 (HDAC IC50 =194 nM: HSP90ce IC50 =153 nM) and compound 26 (HDAC IC50- 360 nM; HSP90 alpha IC50 W 77 nM) displaying most potent HDAC and HSP90a inhibitory activities. Both of these compounds induce HSP70 expression and down regulate HSP90 client proteins which play important roles in the regulation of survival and invasiveness in cancer cells. In addition, compounds 20 and 26 induce acetylation of alpha-tubulin and histone H3. Significantly, compounds 20 and 26 could effectively reduce programmed death-ligand 1 (PD-L1) expression in IFN-gamma treated lung H1975 cells in a dose dependent manner. These findings suggest that dual inhibition of HDAC and HSP90 that can modulate immunosuppressive ability of tumor area may provide a better therapeutic strategy for cancer treatment in the future.

In the case of chemotherapy, the systemic distribution of cytotoxic drugs reduces their efficacy and causes severe side effects due to nonselective toxicity. Photopharmacology allows a novel approach to address these problems because it employs external, local activation of chemotherapeutic agents by using light. The development of photoswitchable histonedeacetylase (HDAC) inhibitors as potential antitumor
癌症治疗存在局限性,这些局限性对患者的生活质量和生存产生重大影响。在化疗的情况下,细胞毒性药物的全身分布会降低其疗效并由于非选择性毒性而导致严重的副作用。光药理学允许一种新的方法来解决这些问题,因为它通过使用光利用外部、局部激活化学治疗剂。本文报道了作为潜在抗肿瘤剂的光开关组蛋白脱乙酰酶 (HDAC) 抑制剂的开发。临床上使用的化学治疗剂伏立诺他、帕比司他和贝立司他的类似物被设计成在其结构中加入了光可切换偶氮苯部分。最有希望的化合物在热力学不太稳定的环境中表现出高抑制效力就 HDAC 活性和 HeLa 细胞增殖而言,顺式形式和反式形式的活性显着降低。这种方法为 HDAC 抑制的局部光激活提供了明确的前景,以避免化疗中的严重副作用。
Design and synthesis of potent dual inhibitors of JAK2 and HDAC based on fusing the pharmacophores of XL019 and vorinostat
potencies against a panel of 4 solidtumor cell lines and 4 hematological cell lines with the most potent compound, 45h, having a cellular IC50 of 70 nM against the multiple myeloma cell line KMS-12-BM. Evidence of both JAK and HDAC pathway inhibition is presented in Hela cells showing that both pathways are modulated. Evidence of apoptosis with two compounds in 4 sold tumor cell lines is also presented
Discovery of <i>N</i>1-(4-((7-Cyclopentyl-6-(dimethylcarbamoyl)-7<i>H</i>-pyrrolo[2,3-<i>d</i>]pyrimidin-2-yl)amino)phenyl)-<i>N</i>8-hydroxyoctanediamide as a Novel Inhibitor Targeting Cyclin-dependent Kinase 4/9 (CDK4/9) and Histone Deacetlyase1 (HDAC1) against Malignant Cancer
A series of novel, highly potent, selective inhibitors targeting both CDK4/9 and HDAC1 have been designed and synthesized. N1-(4-((7-Cyclopentyl-6-(dimethylcarbamoyl)-7H-pyrrolo [2,3-d]pyrimidin-2-yl)amino)phenyl)-N8-hydroxyo ctan ediamide (6e) was discovered. The lead compound 6e with excellent CDK4/9 and HDAC1 inhibitory activity of IC50 = 8.8, 12, and 2.2 nM, respectively, can effectively induce apoptosis of cancer cell lines. The kinase profiling of compound 6e showed excellent selectivity and specificity. Compound 6e induces G2/M arrest in high concentration and G0/G1 arrest in low concentration to prevent the proliferation and differentiation of cancer cells. Mice bared-breast cancer treated with 6e showed significant antitumor efficacy. The insight into mechanisms of 6e indicated that it could induce cancer cell death via cell apoptosis based on CDK4/9 and HDAC1 repression and phosphorylation of p53. Our data demonstrated the novel compound 6e could be a promising drug candidate for cancer therapy.
