Zhang G, Pannucci A, Ivanov A, Switchenko J, Sun S, Sica G, et al.
Cancers (Basel) . 2025 Feb; 17(3). PMID: 39941812
To investigate the preclinical efficacy and identify predictive biomarkers of polo-like kinase 1 (PLK1) inhibitors in small cell lung cancer (SCLC) models. We tested the cytotoxicity of selective PLK1 inhibitors...

Beard J, Love S, Schmitz J, Hoskins A, Koide K
ACS Med Chem Lett . 2024 Dec; 15(12):2225-2230. PMID: 39691513
Meayamycins are synthetic analogs of the natural product FR901464 and exhibit potent anticancer activity against human cancers. They bind SF3B1 and PHF5A, components of the human spliceosome, and they alter...

Pohorilets I, Beard J, Driscoll J, Schmitz J, Koide K
Bioorg Med Chem Lett . 2024 Apr; 104:129739. PMID: 38599298
FR901464 is a natural product that exhibits antiproliferative activity at single-digit nanomolar concentrations in cancer cells. Its tetrahydropyran-spiroepoxide covalently binds the spliceosome. Through our medicinal chemistry campaign, we serendipitously discovered...

Beard J, Bressin R, Markaj P, Schmitz J, Koide K
J Med Chem . 2023 Oct; 66(21):14497-14512. PMID: 37870431
FR901464 is a cytotoxic natural product that binds splicing factor 3B subunit 1 (SF3B1) and PHD finger protein 5A (PHF5A), the components of the human spliceosome. The amide-containing tetrahydropyran ring...

Liu H, Liu H, Zhou Z, Chung J, Zhang G, Chang J, et al.
Cell Commun Signal . 2023 Jun; 21(1):147. PMID: 37337282
Fluoropyridine-based chemotherapy remains the most widely used treatment for colorectal cancer (CRC). In this study, we investigated the mechanism by which the natural product Scutellaria baicalensis (Huang Qin; HQ) and...

Wei N, Burnett J, Crocker D, Huang Y, Li S, Wipf P, et al.
Biochem Pharmacol . 2023 Apr; 212:115564. PMID: 37116665
Cellular protein synthesis is accelerated in human colorectal cancer (CRC), and high expression of protein synthesis regulators in CRC patients is associated with poor prognosis. Thus, inhibition of protein synthesis...

Maguire W, Schmitz J, Scemama J, Czambel K, Lin Y, Green A, et al.
Cancer Chemother Pharmacol . 2021 Jun; 88(4):643-654. PMID: 34164713
Purpose: We investigated the combination of tivantinib, a c-MET tyrosine kinase inhibitor (TKI), and bevacizumab, an anti-VEGF-A antibody. Methods: Patients with advanced solid tumors received bevacizumab (10 mg/kg intravenously every...

Bakkenist C, Czambel R, Lin Y, Yates N, Zeng X, Shogan J, et al.
DNA Repair (Amst) . 2019 Jun; 80:1-7. PMID: 31176958
Since many anticancer therapies target DNA and DNA damage response pathways, biomarkers of DNA damage endpoints may prove valuable in basic and clinical cancer research. Ataxia telangiectasia-mutated (ATM) kinase is...
