STAT3 and non-small cell lung carcinoma: Other terpenoids, such as Ginkgolide C (GGC) and eupatolide isolated from Ginkgo biloba (Ginkgoaceae) leaf and Inula helenium, respectively, could effectively attenuate the phosphorylation of STAT3 and its upstream kinases, demonstrating significant inhibition of NSCLC tumor growth [44,45].
