Design, Synthesis and Biological Evaluation of 4-Aryl-5,7-dihydro-6H-pyrrolo2,3-dpyrimidin-6-one Derivatives as a PI3K α Inhibitor.

Design, Synthesis and Biological Evaluation of 4-Aryl-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one Derivatives as a PI3Kα Inhibitor. Biol Pharm Bull. 2019;42(6):1013-1018 Authors: Hu S, Zhao Z, Ni Y, Xin H, Yan H, Song X Abstract A novel series of 4-aryl-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one derivatives were designed as a phosphoinositide 3-kinase α (PI3Kα) inhibitor by scaffold hopping. The target compounds, characterized by 1H-NMR, 13C-NMR and high resolution (HR)-MS, were synthesized from diethyl malonate and ethyl chloroacetate by nucleophilic substitution, ring-closure, chlorination and Suzuki reaction, etc. The biological activities were evaluated with cytotoxic activity in vitro on Uppsala 87 Malignant Glioma (U87MG) and prostate cancer-3 (PC-3) by Cell Counting Kit-8 (CCK-8). The results showed that compound 9c displayed the higher inhibition than the positive control PI-103, and high PI3Kα inhibitory activity with IC50 of 113 ± 9 nM in the same order of magnitude as BEZ235. In addition, the Log Kow values and molecular docking studies were performed to further investigate the drug-like properties of target compounds and interactions between 9c and PI3Kα.

Abstract Photodynamic therapy is the combination of the initial application of a photosensitive chemical on the skin and then using typically a blue filter light of varying spectrums. This treatment protocol has been more useful and functional than other chemical peels and lasers for a variety of conditions. There has been efficacy in antiviral treatments, such as herpetic lesions; malignant cancers of the head and neck; and lung, bladder, and skin cancers. It has been tested for prostate cancers, cervical cancer, colorectal cancer, lung cancer, breast cancer, esophageal cancer, stomach cancer, pancreatic cancer, ...

Abstract18F-fluciclovine (18F-FACBC) is a radiotracer already studied for prostate cancer, and its potential role in brain tumors (such as glioma) is not yet well investigated despite promising results. The aim of this review is to evaluate the possible diagnostic role of18F-FACBC PET/CT or PET/MRI in patients with gliomas and glioblastomas. A comprehensive literature search of the PubMed/MEDLINE, Scopus, Embase, and Cochrane library databases was conducted to find the relevant published articles about the diagnostic performance of FACBC PET/CT or PET/MRI in patients affected by glioma and/or glioblastoma. Seven papers wer...

In this study, we found that miR-452 was highly expressed in both tumor tissue and gastric cancer cells, and could directly target the cancer suppressor gene EPB41L3 3′-UTR. miR-452 significantly promoted the proliferation, migration and the S-phase arrest of gastric cancer cells, but EPB41L3 as a downstream target gene of miR-452 reversed such promoting effect. While down-regulation of miR-452 expression significantly inhibited the malignant biological behavior of gastric cancer cells, but this inhibitory effect was reversed by EPB41L3 siRNA. In addition, miR-452 in the gastric cancer xenograft model in nude mice co...

Al-Dayel F, Al-Kuraya KS Abstract Sanger Sequencing and immunohistochemistry was employed to investigate the TERT promoter mutations and TERT protein expression with their association to clinicopathological characteristics in over 2200 samples of Middle Eastern origin from 13 different types of cancers. The TERT promoter mutations were most frequently present in bladder cancer (68.6%), followed by central nervous system tumors (28.7%), thyroid cancer (15.4%), prostate cancer (9.3%), endometrial carcinoma (3.7%), rhabdomyosarcoma (1.4%), colorectal cancer (1%), epithelial ovarian carcinoma (0.7%) and breast cancer ...

CONCLUSION: Radiolabelled PSMA imaging seems to be useful in analyzing glioma/glioblastoma. Further studies enrolling a wider population are needed to clarify the real clinical and diagnostic role of radiolabelled PSMA in this setting and its possible position in the diagnostic flow-chart.

Abstract13N-Ammonia (13N-NH3) is widely used positron emission tomography/computed tomography (PET/CT) radiotracer for the measurement of myocardial blood perfusion; the possible role of13N-NH3 PET or PET/CT in oncological disease is not yet clear. Aim of this review is to evaluate the diagnostic performances of13N-NH3 PET in this field. A comprehensive computer literature search of the PubMed/MEDLINE, Scopus, and Embase databases was conducted including articles up to June 2019. Eighteen articles were finally included in the review. From the analyses of the selected studies, the following main findings could be drawn: (1)...

Abstract Integrin targeting has been shown to be an effective approach for anticancer therapy. We engineered a recombinant disintegrin, vicrostatin (VCN), that binds with high affinity and specificity to the Arg-Gly-Asp (RGD) class of integrins, including αvβ3, αvβ5, and α5β1, involved in tumor invasion and metastasis. We used three different delivery modalities to examine anticancer activity of VCN in mouse models of human ovarian cancer, glioma, and prostate cancer. A female mouse model was used to examine the treatment of established ovarian cancer (OC) using VCN delivered intra...
