Identification of an IDO1 inhibitor prodrug that specifically targets tumor tissue / 药学学报

Hypoxia-activated prodrugs that specifically target tumor tissues were designed by attaching the nitro-aromatic ring carrier molecules that can be degraded in the hypoxic microenvironment of the tumor to the hydroxyamidine group of IDO1 inhibitor compound B and epacadostat. Eleven prodrug compounds were synthesized and their structures were confirmed by 1H NMR and HR-MS. Compounds F-1 and F-6, which had a higher stability and drug release rate, were identified by an in vitro stability assay, nitroreductase reduction assay, MTT assay, and an in vivo tumor tissue hypoxia degradation assay, and then evaluated for anti-tumor efficacy in vivo. The results showed that prodrug F-1 inhibited tumor growth by 67.41%, which was significantly higher than 42.31% for the starting drug group. It appeared that the inhibition of IDO1 in the tumor tissue was different from the overall inhibition of IDO1 in vivo. Animal treatment procedures were carried out with the approval of the Animal Care and Use Committee of the Chinese Academy of Medical Sciences and Peking Union Medical College.

This study aimed to explore the anti-tumor activity and mechanisms of action of isorhamnetin, a compound isolated from Astragalus membranaceus, in combination with sorafenib for treatment of renal cell carcinoma (RCC). The anti-tumor activity of isorhamnetin in combination with sorafenib was detected by MTT assay with cells in culture or Renca xenograft model in mice. Western blot was used to study the mechanisms of isorhamnetin in combination with sorafenib. Lymphocyte proliferation assay was also used to investigate the effects of the two drugs in combination. The results indicated that isorhamnetin inhibited the proliferation of RCC cells, with IC50 for A498, 786-O and Renca cell lines with being 31.7, 28.8 and 106.0 μmol·L-1, respectively. Isorhamnetin in combination with sorafenib improved the anti-lymphocyte proliferation activity of sorafenib with the IC50 down to 12.0 μmol·L-1. Isorhamnetin inhibited the growth of RCC in mice slightly with the inhibition efficiency at 26.9%. With 50.0 mg·kg-1 isorhamnetin in combination with 20.0 mg·kg-1 sorafenib, the anti-tumor activity of sorafenib was enhanced, with inhibition of growth rate increased to 60.7%. Meanwhile, isorhamnetin in combination with sorafenib could promote the lymphocytes proliferation in Renca xenograft model. Western blot results showed that combination of isorhamnetin and sorafenib could inhibit c-Raf/MEK/ERK and AKT/mTOR signaling pathways. In conclusion, the combination of isorhamnetin with sorafenib could increase the anti-tumor activity of sorafenib in RCC in vitro and in vivo. The mechanisms may be related to the inhibition of c-Raf/MEK/ERK and AKT/mTOR signaling pathways.

Research progress in epigenetic studies on systemic sclerosis / 中南大学学报(医学版)

Systemic sclerosis (SSc) is an autoimmune disease with unknown etiology, characterized by vasculopathy, inflammation, and extensive fibrosis in the skin and organs. Fibrosis is the hallmark of SSc and contributes to its high mortality. In recent years, with the in-depth study of the epigenetics of SSc (DNA methylation, histone modification, and non-coding RNA), the DNA methylation and miRNA has been the most widely studied. Abnormal DNA methylation can influence the function of vascular endothelial cells, CD4+ T cells, and fibroblasts in SSc. MiRNAs in serum is closely related to autoantibodies, SSc disease activity and complications, and miRNAs in fibroblasts can directly affect the activation of fibroblasts.

The anti-tumor activity and mechanisms of a GLI1 inhibitor FL18 in suppression of glioblastoma growth / 药学学报

The abnormal activation of hedgehog (HH) signaling pathway plays an important role in the development and progression of glioblastoma (GBM). As a transcription factor at the end of the HH pathway, the final effector of glioma-associated oncogene homoglog-1 (GLI1) is an important target in the treatment of GBM. The study was designed to evaluate the anti-tumor activities and mechanisms of a novel GLI1 inhibitor FL18 in GBM. MTT and colony formation assay were performed to determine anti-proliferation activity of FL18 in vitro. The effect of FL18 on cell apoptosis was measured by flow cytometry (FCM) analysis. Transwell experiment was used to explore the inhibitory activity of FL18 in cell invasion. In vivo experiments, the subcutaneously transplanted and orthotopic U-87 MG GBM xenograft model were used to study the activity of FL18 on tumor growth. The optimized dual report gene screening model was used to detect the effect of FL18 on the transcriptional activity of GLI1. Western blot assay was used to study the mechanisms of action of FL18. The results showed that the IC50 of FL18 in glioblastoma was in the nanomole level in vitro. It was observed that 22.5 and 45 mg·kg-1 FL18 reduced the tumor volume with the rate of 55.4% and 89.8% in xenograft model in mice in situ. The IC50 of FL18 on the inhibition of GLI1 transcriptional activity was 3.32×10-11 mol·L-1 analyzed by the optimized dual report gene screening model. By the Western blot experiments, it was proved that FL18 inhibited expression of GLI1 without influencing the upstream canonical HH/SMO signaling and cross-talk oncogenic pathway, such as ERK and AKT signaling. The results also demonstrated that FL18 significantly downregulated GLI1 target genes such as Bcl-2, MMP2 and MMP9 and increased the expression of c-caspase3, c-PARP and Bax. These data suggest that FL18 may generate the anti-glioma activity by inhibition of GLI1.

BACKGROUND:How to improve the stability of artificial cornea in the host and reduce the complications is the current key issues to be solved.Therefore,looking for an ideal biocompatible scaffold material is still the focus of the study.OBJECTIVE:To explore the biocompatibility of nano-hydroxyapatite (nHA)/polyvinyl alcohol (PVA) porous composite hydrogel and pure PVA hydrogel as artificial corneal materials.METHODS:Inverted microscope was used to observe cell growth of rabbit corneal stromal fibroblasts when cultured with nHA/PVA composite hydrogel extract or PVA extract for 48 hours.MTT method was used to detect the relative proliferation rate of rabbit corneal stromal fibroblasts cultured with nHA/PVA composite hydrogel extract or PVA extract.Systemic toxicity,allergies,pyrogen reaction and deaths were observed in New Zealand white rabbits at 48 hours after artificial corneal implantation.ELISA and hematoxylin-eosin staining were used to detect changes in serum inflammatory factors at 4 weeks after artificial corneal implantation.Slit-lamp examination was performed to observe corneal or conjunctival hyperemia/edema and corneal neovascularization at 1-4 weeks after corneal implantation.Corneal neovascularization time and neovascularization area were detected after the two materials were implanted.RESULTS AND CONCLUSION:The cells were sparse and grew slowly at 48 hours after culture in nHA/PVA composite hydrogel or PVA extract as compared with the blank control group.The cell growth in the nHA/PVA composite hydrogel group was better than that in the PVA group.The relative cell proliferation rate was significantly decreased at different time after culture in nHA/PVA composite hydrogel or PVA extract compared with the blank control group (P ＜ 0.05),and the relative cell proliferation rate in the nHA/PVA composite hydrogel group was significantly higher than that in the PVA group (P ＜ 0.05).There were two rabbits appearing to have allergic reaction,but no one presenting with pyrogen reaction and death in the nHA/PVA composite hydrogel group;and there were two rabbits appearing to have allergic reaction,and two appearing to have pyrogen reaction,but no death in the PVA group at 48 hours after implantation.The inflammatory factor levels were increased significantly in the nHA/PVA composite hydrogel group and PVA group compared with the control group (P ＜ 0.05),and inflammatory infiltration was milder in the nHA/PVA composite hydrogel group than the PVA group at 4 weeks after implantation (P ＜ 0.05).Corneal neovascularization appeared later in the nHA/PVA composite hydrogel group than the PVA group,and the neovascularization area was also smaller in the nHA/PVA composite hydrogel group than the PVA group (P ＜ 0.05).Taken together,the biocompatibility of nHA/PVA composite hydrogel is superior to that of pure PVA when they are used as artificial cornea materials,which provides a scientific basis for artificial cornea material innovation and extensive clinical application.

Clinical research status and progress of acquired syphilis uveitis / 中华眼底病杂志

Acquired syphilis uveitis,due to lack of the characteristic features,presents with various types.The most common type is posterior uveitis and panuveitis,including chorioretinitis,retinal vasculitis,optic nerve retinitis.The diagnosis and assessment of response to treatment depends mainly on the serological diagnostic tests,including nontreponemal and treponemal test.Acquired syphilis uveitis often presents with manifestations similar to various types of uveitis,especially to autoimmune uveitis and other infectious uveitis,so differential diagnosis is important.The gold standard treatment for active syphilitic uveitis is penicillin G,or doxycycline if patient is allergy to penicillin.Clinically misdiagnosis and delayed treatment may result in irreversible visual impairment and severe systemic and eye complications.However such timely treatment always has a good prognosis.
