DataSheet4_Synthesis and Antitumor Activity of Erlotinib Derivatives Linked With 1,2,3-Triazole.zip

Cervical cancer is one of the most important cause of cancer-related death and presents a major public health problem in many countries. To search for more novel antitumor agents against cervical cancer, 14 erlotinib-linked 1,2,3-triazole compounds were designed, synthesized, and evaluated for their anti-tumor activity. The compounds were confirmed by 1H NMR, 13C NMR, and high-resolution mass spectra (HR MS). Antitumor activity assay results indicated that six of those compounds have remarkable inhibitory activity against human cervical cancer HeLa cells in vitro, among which compound 4m was the most potent with IC50 of 3.79 μM, and compounds 4k, 4i, 4l, 4d, and 4n also demonstrated remarkable antitumor activity with IC50 of 3.79, 4.16, 4.36, 7.02, and 8.21 μM. We found three of the most potent compounds 4d, 4k, and 4l induced potent apoptosis and cell cycle arrest in HeLa cells, and compounds 4d and 4l significantly restrained the cell colony formation and showed moderate epidermal growth factor receptor (EGFR) inhibitory activity with IC50 of 13.01 and 1.76 μM. Therefore, these experiments indicate that these erlotinib-linked 1,2,3-triazole compounds are potential to act as effective anticancer agents against cervical cancer.</p

Table1_Discovery of Novel HPK1 Inhibitors Through Structure-Based Virtual Screening.DOCX

Hematopoietic progenitor kinase (HPK1) is a negative regulator of T-cell receptor and B-cell signaling, which has been recognized as a novel antitumor target for immunotherapy. In this work, Glide docking-based virtual screening and kinase inhibition assay were performed to identify novel HPK1 inhibitors. The kinase inhibition assay results demonstrated five compounds with IC50 values below 20 μM, and the most potent one (compound M074-2865) had an IC50 value of 2.93 ± 0.09 μM. Molecular dynamics (MD) simulations were performed to delve into the interaction of sunitinib and the identified compound M074-2865 with the kinase domain of HPK1. The five compounds identified in this work could be considered promising hit compounds for further development of HPK1 inhibitors for immunotherapy.</p

DataSheet2_Discovery of a Series of Theophylline Derivatives Containing 1,2,3-Triazole for Treatment of Non-Small Cell Lung Cancer.ZIP

Chemotherapy is the most common clinical treatment for non-small cell lung cancer (NSCLC), but low efficiency and high toxicity of current chemotherapy drugs limit their clinical application. Therefore, it is urgent to develop hypotoxic and efficient chemotherapy drugs. Theophylline, a natural compound, is safe and easy to get, and it can be used as a modified scaffold structure and hold huge potential for developing safe and efficient antitumor drugs. Herein, we linked theophylline with different azide compounds to synthesize a new type of 1,2,3-triazole ring-containing theophylline derivatives. We found that some theophylline1,2,3-triazole compounds showed a good tumor-suppressive efficacy. Especially, derivative d17 showed strong antiproliferative activity against a variety of cancer cells in vitro, including H460, A549, A2780, LOVO, MB-231, MCF-7, OVCAR3, SW480, and PC-9. It is worth noting that the two NSCLC cell lines H460 H and A549 are sensitive to compound d17 particularly, with IC50 of 5.929 ± 0.97 μM and 6.76 ± 0.25 μM, respectively. Compound d17 can significantly induce cell apoptosis by increasing the ratio of apoptotic protein Bax/Bcl-2 by downregulating the expression of phosphorylated Akt protein, and it has little toxicity to normal hepatocyte cells LO2 at therapeutic concentrations. These data indicate that these theophylline acetic acid-1,2,3-triazole derivatives may be potential drug candidates for anti-NSCLC and are worthy of further study.</p
