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.

1.E6201 [(3S,4R,5Z,8S,9S,11E)-14-(ethylamino)-8, 9,16-trihydroxy-3,4-dimethyl-3,4,9,19-tetrahydro-1H-2-benzoxacyclotetradecine-1,7(8H)-dione], a novel kinase inhibitor of mitogen-activated protein kinase/extracellular signal-regulated kinase kinase (MEK)-1 and MEK kinase-1: in vitro characterization of its anti-inflammatory and antihyperproliferative activities.

The goal of this study is to identify a novel inhibitor with anti-inflammatory and antiproliferative properties for the treatment of psoriasis. Compound f152A1 [(3S,5Z,8S,11E)-8,9,16-trihydroxy-14-methoxy-3-methyl-3,4,9,10-tetrahydro-1H-benzo[c][1]oxacyclotetradecine1,7(8H)-dione] was identified as the main active metabolite with strong inhibitory activity against tumor necrosis factor-alpha (TNFalpha) transcription in a fraction originated from the fermentation broth of the fungus Curvularia verruculosa. Although active in cell-based assays, f152A1 was unstable in plasma and liver microsome preparations, thus limiting its pharmaceutical utilization. To improve the metabolic properties of f152A1, a medicinal chemistry program was undertaken, resulting in the generation of over 400 analogs of f152A1. Eventually, E6201 [(3S,4R,5Z,8S,9S,11E)-14-(ethylamino)-8,9,16-trihydroxy-3,4-dimethyl-3,4,9,19-tetrahydro-1H-2-benzoxacyclotetradecine-1,7(8H)-dione] was identified as a promising analog in this series.
2.Pharmacokinetic characterization of a natural product-inspired novel MEK1 inhibitor E6201 in preclinical species.

PURPOSE: E6201 is a natural product-inspired novel inhibitor of mitogen-activated protein kinase/extracellular signal-regulated kinase kinase-1 (MEK1) and other kinases and is currently under development as an anticancer (parenteral administration) and antipsoriasis agent (topical application). In vitro and in vivo preclinical studies were performed to characterize the pharmacokinetics of E6201. Allometric scaling was applied to predict human pharmacokinetics of E6201.
3.Discovery of anti-inflammatory clinical candidate E6201, inspired from resorcylic lactone LL-Z1640-2, III.

Inspired by natural product, LL-Z1640-2, clinical candidate, E6201 (22) 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.
4.Phase III, randomized study of gemcitabine and oxaliplatin versus gemcitabine (fixed-dose rate infusion) compared with gemcitabine (30-minute infusion) in patients with pancreatic carcinoma E6201: a trial of the Eastern Cooperative Oncology Group.

PURPOSE: Single-agent gemcitabine (GEM) is standard treatment of metastatic pancreatic cancer. Fixed-dose rate (FDR) GEM and GEM plus oxaliplatin have shown promise in early clinical trials. E6201 was designed to compare overall survival (OS) of standard weekly GEM 1,000 mg/m(2)/30 minutes versus GEM FDR 1,500 mg/m(2)/150 minutes or GEM 1,000 mg/m(2)/100 minutes/day 1 plus oxaliplatin 100 mg/m(2)/day 2 every 14 days (GEMOX).
