Nilotinib (AMN107) is a Bcr-Abl tyrosine kinase inhibitor with oral activity. Nilotinib has antitumor activity and may be used for the treatment of Imatinib-resistant chronic myelogenous leukemia (CML).

Anticanceragent 259 (Compound 3g) is a telmisartan-based cell death regulator that disrupts the STAT5 signaling pathway, thereby increasing the sensitivity of resistant cells to imatinib, with an SC50 of 1.5 μM.

MPT0B002 is a microtubule inhibitor that acts by downregulating T315I mutant Bcr-Abl and inducing apoptosis of imatinib-resistant chronic myeloid leukemia cells.

HS-438 inhibits imatinib-resistant BCR-ABL T315I mutation in chronic myeloid leukemia.

PPARγ agonist 3, also known as Compound 18a, is a potent and selective agonist of PPARγ. This compound does not exhibit cytotoxicity towards both non-resistant and resistant cells. Notably, PPARγ agonist 3 demonstrates antitumor efficacy exclusively when co-administered with Imatinib [1].

PPARγ agonist 4 (Compound 18b), a potent and selective PPARγ agonist, demonstrates antitumor efficacy only when used in conjunction with Imatinib and does not exhibit cytotoxic effects on either non-resistant or resistant cells [1].

AKI603 is a novel small molecule inhibitor of Aurora kinase A (AurA)(IC50 = 12.3 nM). AKI603 is developed to overcome resistance mediated by BCR-ABL-T315I mutation. AKI603 exhibits strong anti-proliferative activity in leukemic cells[1][2].

Nilotinib hydrochloride dihydrate is a small-molecule tyrosine kinase inhibitor approved for the treatment of imatinib-resistant chronic myelogenous leukemia.

AP23464 is a potent adenosine 5'-triphosphate (ATP)-based inhibitor of Src and Abl kinases, displays antiproliferative activity against a human CML cell line and Bcr-Abl-transduced Ba F3 cells (IC(50) = 14 nM. AP23464 ablates Bcr-Abl tyrosine phosphorylation, blocks cell cycle progression, and promotes apoptosis of Bcr-Abl-expressing cells. Biochemical assays with purified glutathione S transferase (GST)-Abl kinase domain confirmed that AP23464 directly inhibits Abl activity. Importantly, the low nanomolar cellular and biochemical inhibitory properties of AP23464 extend to frequently observed imatinib mesylate-resistant Bcr-Abl mutants, including nucleotide binding P-loop mutants Q252H, Y253F, E255K, C-terminal loop mutant M351T, and activation loop mutant H396P. AP23464 was ineffective against mutant T315I, an imatinib mesylate contact residue. The potency of AP23464 against imatinib mesylate-refractory Bcr-Abl and its distinct binding mode relative to imatinib mesylate warr......

ON012380 is a non-ATP-competitive Bcr-Abl inhibitor, potently inhibiting imatinib-resistant Bcr-Abl mutants such as T315I.

PHA-680626 is a potent and selective PLK inhibitor. PHA-680626 exhibits anti-proliferative and pro-apoptotic activity on Imatinib-resistant chronic myeloid leukemia cell lines and primary CD34+ cells by inhibition of both Bcr-Abl tyrosine kinase and Aurora kinases. PHA-680626 inhibits Plk1 (IC50 = 0.53 μM), Plk2 (IC50 = 0.07 μM) and Plk3 (IC50 = 1.61 μM).

Nilotinib dihydrochloride dihydrate is a small-molecule tyrosine kinase inhibitor approved for the treatment of imatinib-resistant chronic myelogenous leukemia.

Nilotinib N-oxide is a small-molecule tyrosine kinase inhibitor approved for the treatment of imatinib-resistant chronic myelogenous leukemia.

ON044580 is an effective non-ATP-competitive inhibitor of JAK2, characterized as an α-benzoylstyrylbenzyl thioether. It exhibits IC50 values of 1.23 μM for wild type JAK2 and 1.09 μM for the V617F mutation. The compound inhibits JAK2 kinase activity by binding to the STAT-5 binding domain or the allosteric site of JAK2. In JAK2V617F-positive leukemia cells, ON044580 suppresses proliferation and induces apoptosis in Imatinib-resistant chronic myeloid leukemia (CML) cells. It also inhibits both wild type and T315I mutant forms of the BCR-ABL kinase. ON044580 is used in research for myeloproliferative diseases characterized by abnormal JAK STAT signaling.

CHMFL-48, an orally active inhibitor of BCR-ABL kinase, demonstrates efficacy against both the wild-type (wt) and various imatinib-resistant mutants. It exhibits potent inhibitory activity, with IC 50 values of 1 nM for the ABL wild-type and 0.8 nM for the ABL T315I mutant. CHMFL-48 operates by inhibiting the autophosphorylation of both wild-type and mutant BCR-ABL, affecting downstream signaling mediators including STAT5 and CRKL. This disruption leads to cell cycle arrest and triggers apoptosis. Given its properties, CHMFL-48 is a promising candidate for research on chronic myeloid leukemia (CML).

Ladanein is a phytochemicals inhibitor that is known to disrupt the interactions of core and other hepatitis C virus (HCV) proteins.Ladanein possesses free radicals DPPH and ABTS +.scavenging activity, it also displays moderate (20-40 microM) activities against K562, K562R (imatinib-resistant), and 697 human leukemia cell lines.
