Targeting tumour microenvironment by tyrosine kinase inhibitor

Exploration of Receptor Tyrosine Kinase Inhibitor for Molecular Targeting Therapy

AL3810, a multi-tyrosine kinase inhibitor, exhibits potent anti-angiogenic and anti-tumour activity via targeting VEGFR, FGFR and PDGFR

Angiogenesis plays an important role in neoplastic transformation and progression as well as in the metastasis process of most human cancers. Herein, we identified AL3810 as a novel and orally bioavailable small molecular inhibitor with potent inhibitory activity against multiple tyrosine kinases involved in the process of angiogenesis. We found that AL3810 substantially inhibited the autophosp...

Tyrosine kinase inhibitor-induced macrocytosis.

BACKGROUND The tyrosine kinase inhibitors (TKI) sunitinib and imatinib were shown to induce macrocytosis in patients with renal cell cancer (RCC) and gastrointestinal stromal tumors (GIST), presumably through inhibition of the c-KIT dependent signaling pathway of erythroid progenitor cells of the bone marrow. PATIENTS AND METHODS Hematology charts of patients with RCC, breast cancer (BC), GIS...

Inhibition of c-kit receptor tyrosine kinase activity by STI 571, a selective tyrosine kinase inhibitor.

STI 571 (formerly known as CGP 57148B) is a known inhibitor of the c-abl, bcr-abl, and platelet-derived growth-factor receptor (PDGFR) tyrosine kinases. This compound is being evaluated in clinical trials for the treatment of chronic myelogenous leukemia. We sought to extend the activity profile of STI 571 by testing its ability to inhibit the tyrosine kinase activity of c-kit, a receptor struc...

Clostridial Spores for Cancer Therapy: Targeting Solid Tumour Microenvironment

Solid tumour accounts for 90% of all cancers. The current treatment approach for most solid tumours is surgery, however it is limited to early stage tumours. Other treatment options such as chemotherapy and radiotherapy are non-selective, thus causing damage to both healthy and cancerous tissue. Past research has focused on understanding tumour cells themselves, and conventional wisdom has aime...
