Description: E6201 is a synthetic, fungal metabolite analogue inhibitor of mitogen-activated protein kinase kinase 1 (MEK-1) and mitogen-activated protein kinase kinase kinase 1 (MEKK-1) with potential antipsoriatic and antineoplastic activities. MEK-1/MEKK-1 inhibitor E6201 specifically binds to and inhibits the activities of MEK-1 and MEKK-1, which may result in the inhibition of tumor cell proliferation. MEK-1 and MEKK-1 are key components in the RAS/RAF/MEK/MAPK signaling pathway, which regulates cell proliferation and is frequently activated in human cancers.

Inspired by natural product, LL-Z1640-2, clinical candidate, E6201 was discovered in a medicinal chemistry effort through total synthesis. The modification on C14-position to N-alkyl substitution showed to be potent in vitro and orally active in vivo in anti-inflammatory assays. Phase I clinical trails showed that E6201 MTD of 320 mg/m2 IV once weekly for 3 out of a 4-week cycle was well tolerated in patients with advanced solid tumors.
