The article was titled 《Discovery of 1,3,4-oxadiazole derivatives as potential antitumor agents inhibiting the programmed cell death-1/programmed cell death-ligand 1 interaction》, and you may find the article in Bioorganic & Medicinal Chemistry.Application of 16982-21-1 The information in the text is summarized as follows:
Inhibition of the programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) interaction by small-mol. inhibitors is emerging cancer immunotherapy. A series of novel 1,3,4-oxadiazole derivatives were designed, synthesized, and evaluated for their activities in vitro and vivo to find potent inhibitors of the PD-1/PD-L1 interaction. Among them, compound II-14 exhibited outstanding biochem. activity, with an IC50 of 0.0380 μM. Importantly, compound II-14, with a TGI value of 35.74 %, had more potent efficacy in a mouse tumor model compared to that in the control group. Surprisingly, when compound II-14 combined with 5-FU in a mouse tumor model having a TGI value of 64.59 %, which showed potential anti-tumor synergistic effects. Furthermore, immunohistochem. anal. demonstrated that compound II-14 activated the immune microenvironment by promoting the infiltration of CD4+ T cells into tumor tissues. These results indicate that compound II-14 is a promising lead compound for further development of small-mol. PD-1/PD-L1 inhibitors for cancer therapy. In addition to this study using Ethyl 2-amino-2-thioxoacetate, there are many other studies that have used Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Application of 16982-21-1) was used in this study.
Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.Application of 16982-21-1
