Background on GNF-7

IC50: The IC50 of GNF-7 is 0.005, 0.001, and 0.008 μM in Colo205, SW620, and TrkC-Ba/F3 cells, respectively.

GNF-7 is the type-II inhibitor of T315I-Bcr-Abl [1]. BCR-ABL, constitutively activated tyrosine kinase, is an oncogene associated with chronic myelogenous leukemia (CML) and some cases of acute lymphocytic leukemia in humans.

In vitro: GNF-7 showed excellent growth inhibitory activity against some human cancer cells. The IC50 of GNF-7 is 0.005, 0.001, and 0.008 μM when tested in Colo205, SW620, and TrkC-Ba/F3 cell line, respectively. GNF-7 showed little effect on HEK293T cells, a normal cell line [1]. After treated for 24 h (7.5 mg/kg QD or 15 mg/kg QD), GNF-7 significantly decreased disease burden in mice and prolonged overall survival compared to vehicle-controls [2].

In vivo: In acute myelogenous leukemia and lymphoblastic leukemia models, GNF-7 potently and selectively inhibited NRAS-dependent cells [2]. In the T315I-Bcr-Abl-Ba/F3 cell line bioluminescent xenograft mouse model, oral administration of GNF-7 with 10 or 20 mg/kg exhibited significant efficacy against T315I-Bcr-Abl without appreciable toxicity [1].

First SAR Study for Overriding NRAS Mutant Driven Acute Myeloid Leukemia.[Pubmed:30153003]

J Med Chem. 2018 Sep 27;61(18):8353-8373.

GNF-7, a multitargeted kinase inhibitor, served as a dual kinase inhibitor of ACK1 and GCK, which provided a novel therapeutic strategy for overriding AML expressing NRAS mutation. This SAR study with GNF-7 derivatives, designed to target NRAS mutant-driven AML, led to identification of the extremely potent inhibitors, 10d, 10g, and 11i, which possess single-digit nanomolar inhibitory activity against both ACK1 and GCK. These substances strongly suppress proliferation of mutant NRAS expressing AML cells via apoptosis and AKT/mTOR signaling blockade. Compound 11i is superior to GNF-7 in terms of kinase inhibitory activity, cellular activity, and differential cytotoxicity. Moreover, 10k possessing a favorable mouse pharmacokinetic profile prolonged life-span of Ba/F3-NRAS-G12D injected mice and significantly delayed tumor growth of OCI-AML3 xenograft model without causing the prominent level of toxicity found with GNF-7. Taken together, this study provides insight into the design of novel ACK1 and GCK dual inhibitors for overriding NRAS mutant-driven AML.

Discovery of 2-((3-Amino-4-methylphenyl)amino)-N-(2-methyl-5-(3-(trifluoromethyl)benzamido)phe nyl)-4-(methylamino)pyrimidine-5-carboxamide (CHMFL-ABL-053) as a Potent, Selective, and Orally Available BCR-ABL/SRC/p38 Kinase Inhibitor for Chronic Myeloid Leukemia.[Pubmed:26789553]

J Med Chem. 2016 Mar 10;59(5):1984-2004.

Starting from a dihydropyrimidopyrimidine core scaffold based compound 27 (GNF-7), we discovered a highly potent (ABL1: IC50 of 70 nM) and selective (S score (1) = 0.02) BCR-ABL inhibitor 18a (CHMFL-ABL-053). Compound 18a did not exhibit apparent inhibitory activity against c-KIT kinase, which is the common target of currently clinically used BCR-ABL inhibitors. Through significant suppression of the BCR-ABL autophosphorylation (EC50 about 100 nM) and downstream mediators such as STAT5, Crkl, and ERK's phosphorylation, 18a inhibited the proliferation of CML cell lines K562 (GI50 = 14 nM), KU812 (GI50 = 25 nM), and MEG-01 (GI50 = 16 nM). A pharmacokinetic study revealed that 18a had over 4 h of half-life and 24% bioavailability in rats. A 50 mg/kg/day dosage treatment could almost completely suppress tumor progression in the K562 cells inoculated xenograft mouse model. As a potential useful drug candidate for CML, 18a is under extensive preclinical safety evaluation now.

Hybrid pyrimidine alkynyls inhibit the clinically resistance related Bcr-Abl(T315I) mutant.[Pubmed:26195136]

Bioorg Med Chem Lett. 2015 Sep 1;25(17):3458-63.

A series of pyrimidine alkynyl derivatives were designed and synthesized as new Bcr-Abl inhibitors by hybriding the structural moieties from GNF-7, ponatinib and nilotinib. One of the most potent compounds 4e strongly suppresses Bcr-Abl(WT) and Bcr-Abl(T315I) kinase with IC50 values of 5.0 and 9.0 nM, and inhibits the proliferation of K562 and murine Ba/F3 cells ectopically expressing Bcr-Abl(T315I) cells with IC50 values of 2 and 50 nM, respectively. It also displays good pharmacokinetics properties with an oral bioavailability of 35.3% and T(1/2) value of 48.7 h, and demonstrates significantly suppression on tumor growth in xenografted mice of K562 and Ba/F3 cells expressing Bcr-Abl(T315I). These inhibitors may serve as lead compounds for further developing new anticancer drugs overcoming the clinically acquired resistance against current Bcr-Abl inhibitors.

Identification of novel therapeutic targets in acute leukemias with NRAS mutations using a pharmacologic approach.[Pubmed:25833960]

Blood. 2015 May 14;125(20):3133-43.

Oncogenic forms of NRAS are frequently associated with hematologic malignancies and other cancers, making them important therapeutic targets. Inhibition of individual downstream effector molecules (eg, RAF kinase) have been complicated by the rapid development of resistance or activation of bypass pathways. For the purpose of identifying novel targets in NRAS-transformed cells, we performed a chemical screen using mutant NRAS transformed Ba/F3 cells to identify compounds with selective cytotoxicity. One of the compounds identified, GNF-7, potently and selectively inhibited NRAS-dependent cells in preclinical models of acute myelogenous leukemia and acute lymphoblastic leukemia. Mechanistic analysis revealed that its effects were mediated in part through combined inhibition of ACK1/AKT and of mitogen-activated protein kinase kinase kinase kinase 2 (germinal center kinase). Similar to genetic synthetic lethal approaches, these results suggest that small molecule screens can be used to identity novel therapeutic targets in cells addicted to RAS oncogenes.

A type-II kinase inhibitor capable of inhibiting the T315I "gatekeeper" mutant of Bcr-Abl.[Pubmed:20604564]

J Med Chem. 2010 Aug 12;53(15):5439-48.

The second generation of Bcr-Abl inhibitors nilotinib, dasatinib, and bosutinib developed to override imatinib resistance are not active against the T315I "gatekeeper" mutation. Here we describe a type-II T315I inhibitor 2 (GNF-7), based upon a 3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one scaffold which is capable of potently inhibiting wild-type and T315I Bcr-Abl as well as other clinically relevant Bcr-Abl mutants such as G250E, Q252H, Y253H, E255K, E255V, F317L, and M351T in biochemical and cellular assays. In addition, compound 2 displayed significant in vivo efficacy against T315I-Bcr-Abl without appreciable toxicity in a bioluminescent xenograft mouse model using a transformed T315I-Bcr-Abl-Ba/F3 cell line that has a stable luciferase expression. Compound 2 is among the first type-II inhibitors capable of inhibiting T315I to be described and will serve as a valuable lead to design the third generation Bcr-Abl kinase inhibitors.

Description

GNF-7 inhibits Bcr-Abl WT and Bcr-Abl T315I with IC50 of 133 nM and 61 nM, respectively.
