Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 10 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 640 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

Cladribine is an adenosine deaminase inhibitor for U266, RPMI8226, and MM1.S cells with IC50 of approximately 2.43 μM, 0.75 μM, and 0.18 μM, respectively.

Targets

Adenosine deaminase (MM1.S cells) ^[1]	Adenosine deaminase (RPMI8226 cells) ^[1]	Adenosine deaminase (U266 cells) ^[1]
0.18 μM	0.75 μM	2.43 μM

In vitro

Cladribine exerts remarkable activity in hairy cell leukemia (HCL), a chronic B-cell lymphoproliferative disorder, producing prolonged complete remissions. Cladribine induces accumulation of DNA strand breaks, and subsequently activates the tumor suppressor p53 in lymphocytes. Cladribine may modulate STAT3 activity in MM cells. Cladribine inhibits proliferation/survival of U266, RPMI8226 and MM1.S cells in a dose-dependent manner. While U266 is the least sensitive cell line, MM1.S is the most sensitive one to cladribine. Treatment with cladribine gradually increases the percentage of cells in the G1 phase of the cell cycle and reduces the percentage of cells in S phase. Cladribine appears to increase G2-M phase in U266 cells upon 24 hour-treatment. A dose-dependent increase in apoptosis induced by cladribine is seen in both RPMI8226 and MM1.S cells. Treatment with cladribine at 0.2 μM dramatically induces activation of caspase-3, -8, and -9 and PARP cleavage in a time-dependent manner in MM1.S. Cladribine significantly decreases the phospho-STAT3 (P-STAT3) levels in a dose-dependent manner, but has no effect on the total STAT3 protein levels. ^[1] Cladribine possesses concentration-dependent apoptosis-inducing potential in the HSB2 cells. ^[2] Cladribine inhibits growth of primary mast cell (MC) and the MC line HMC-1 in a dose-dependent manner, with lower IC50 values recorded in HMC-1.2 cells harboring KIT D816V compared to HMC-1.1 cells lacking KIT D816V. ^[3] Cladribine decreases the migratory capacity of CD14⁺ monocytes, as well as of CD4⁺ and CD8⁺ T lymphocytes. ^[4]

In vivo

Cladribine (0.7-3.5 mM) and/or diltiazem (2.4 mM), is injected intraperitoneally into adult zebrafish and red blood cell (RBC) lysates are assayed by HPLC for levels of purine nucleotides (e.g. ATP), potential biomarkers of cardiovascular health. Diltiazem increased RBC ATP concentrations, which are inhibited by co-injection of cladribine. ^[5] Plasma concentrations of Cladribine decreases rapidly following a biphasic decline after both ia and s.c. administrations. The AUC and t _1/2 beta after a single 1 mg/kg ia and 2 mg/kg s.c. injection of Cladribine are 0.66 vs 1.2 μg × h/mL and 3.5 vs 4.5 hours, respectively. ^[6]

Features

Cladribine is primarily active in lymphoid tissues.

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines U266, RPMI8226 and MM1.S Concentrations 0 μM - 32 μM Incubation Time 72 hours Method The non-radioactive cell proliferation kit is used to determine cell viability. In brief, Human MM cell line U266, RPMI8226 and MM1.S are seeded onto 96-well plates with either 0.1 mL complete medium (5% FBS) as control, or 0.1 mL of the same medium containing a series of doses of cladribine, and incubated for 72 hours. After reading all wells at 490 nm with a micro-plate reader, the percentages of surviving cells from each group relative to controls, defined as 100% survival, are determined by reduction of MTS.
