Halociline, a derivative of alkaloids that can be isolated from the marine fungus Penicillium griseofulvum, targets MAPK1, MMP-9, and PIK3CA in gastric cancer cells. This action is potentially mediated by diverse pathways, including cancer, lipid metabolism, atherosclerosis, and EGFR tyrosine kinase inhibitor resistance. Halociline possesses antimicrobial, antioxidant, and biofilm inhibitory activities [1] [2].

7-oxo Staurosporine is an antibiotic originally isolated from S. platensis with diverse biological activites. It inhibits PKC, PKA, phosphorylase kinase, EGFR, and c-Src in vitro (IC50s = 9, 26, 5, 200, and 800 nM, respectively). 7-oxo Staurosporine induces cell cycle arrest in the G2/M phase in human leukemia K562 cells with a minimal effective dose (MED) of 30 ng/ml. It is cytotoxic to P388 mouse leukemia cells that are resistant and susceptible to doxorubicin . 7-oxo Staurosporine inhibits growth of the mycelial, but not yeast form of C. albicans, C. krusei, C. tropicalis, and C. lusitaniae (MICs = 3.1-25 μg/ml). It increases sphingomyelin synthesis in CHO-K1 cells when used at a concentration of 50 nM.

ASK120067 is a potent and orally active inhibitor of EGFRT790M (IC50:0.3 nM) with selectivity over EGFRWT (IC50:6.0 nM). ASK120067 is a third-generation EGFR-TKI for the research of non-small cell lung cancer (NSCLC)[1]. In the in vitro kinase assay ASK120067 potently inhibits the EGFR L858R T790M and EGFR T790M resistant mutants with IC50 values of 0.3 nM and 0.5 nM, respectively, as well as the EGFRexon19del sensitizing mutant (IC50= 0.5 nM). The 50 of ASK120067 against wild-type EGFR (EGFRWT) is 6 nM[1].ASK120067 selectively inhibits the growth of EGFR-mutant cell lines and exhibits potent antiproliferative activity in the mutant EGFR NSCLC cells, with IC50 values of 12 nM, 6 nM and 2 nM against NCI-H1975 (T790M mutation), PC-9, and HCC827 cells (sensitizing mutations), respectively. However, it shows moderate or weak anti-growth activities in A431, LoVo and A549 cells (EGFRWT), with IC50 values ranging from 338 nM to 1541 nM[1].ASK120067 (0.1-100 nM) inhibits the phosphorylation of EGFR at Tyrosine residue 1068 and its downstream signaling proteins AKT and ERK in NCI-H1975 cells (EGFRL858R T790M) even at low dosage (0.1-1 nM).
