Olitigaltin
Based on 13 publication(s) in Google Scholar
Olitigaltin (TD139) is a high-affinity Galectin-3 inhibitor with a Kd value of 14 nM. Olitigaltin inhibits the activity of the AKT/β-catenin pathway, induces Apoptosis, and downregulates SREBP1 expression. Olitigaltin enhances the phosphorylation level of ERK. Olitigaltin alleviates bleomycin (HY-17565A)-induced advanced pulmonary fibrosis in mice. Olitigaltin delays the onset of diabetes, and improves glucose tolerance and serum insulin levels. Olitigaltin alleviates liver injury. Olitigaltin maintains the structure of hippocampal excitatory synapses, restores γ-wave power in the hippocampal CA1 region, inhibits hippocampal neuroinflammation, and improves cognitive function in neuroinflammation models. Olitigaltin can be used in research related to thyroid cancer, idiopathic pulmonary fibrosis, type 1 diabetes, hepatitis, and cognitive dysfunction induced by neuroinflammation.
