Our previous studies indicated that K562 cells loaded with arabinosyl-2-fluoroadenine 5'-triphosphate (F-ara-ATP) accumulated arabinosylcytosine 5'-triphosphate (ara-CTP) at a threefold higher rate compared to the control cells. In the present study lymphocytes were obtained from patients with chronic lymphocytic leukemia before and after F-ara-A monophosphate therapy. The rate of ara-CTP accum...
PURPOSE To compare the receipt of clofarabine plus cytarabine (Clo+Ara-C arm) with cytarabine (Ara-C arm) in patients ≥ 55 years old with refractory or relapsed acute myelogenous leukemia (AML). PATIENTS AND METHODS Patients were randomly assigned to receive either clofarabine (Clo) 40 mg/m(2) or a placebo followed by Ara-C 1 g/m(2) for five consecutive days. The primary end point was overall...
2-Arachidonoyl-glycerol (2-Ara-GI) has been isolated from various tissues and identified as an endogenous ligand for both cannabinoid receptors, CB1 and CB2. Here we report that in spleen, as in brain and gut, 2-Ara-GI is accompanied by several 2-acyl-glycerol esters, two major ones being 2-linoleoyl-glycerol (2-Lino-Gl) and 2-palmitoyl-glycerol (2-Palm-Gl). These two esters do not bind to the ...
6-Methoxypurine arabinoside (ara-M) exhibits potent activity against varicella-zoster virus (VZV) as a result of ara-M's anabolism to the triphosphate of adenine arabinoside (ara-ATP) in VZV-infected cells. The adenosine deaminase inhibitor erythro-9-(2-hydroxy-3-nonyl)adenine (EHNA) enhanced the formation of ara-ATP by inhibiting ara-M demethoxylation. In contrast, deoxycoformycin and coformyc...
The minimum inhibitory concentration (MIC) of adenine arabinoside (ara-A) in rabbit kidney microtiter tissue cultures (RK-13) to a prototype strain of herpes simplex virus, type 1 (E115) based upon inhibition of cytopathic effects is 1.5 mug/ml. In this system, the MIC of arabinosylhypoxanthine (ara-Hx), the major in vivo metabolic derivative of ara-A, is 75 mug/ml. Inhibition of cytopathic eff...
An anti-tumour agent of cytarabine (ara-C) was conjugated with a 2-oxopropyl group at the N(4) position to obtain a radiation-activated prodrug (oxo-ara-C) that targeted hypoxic tumour tissues with selective cytotoxicity. The parent anti-tumour agent, ara-C, was confirmed to be released from oxo-ara-Cvia one-electron reduction upon hypoxic X-ray treatment. The prodrug oxo-ara-C had dramatically...
