The effects of the chiral isomers of erythro- and threo-9-(2-hydroxy-3-nonyl)adenines (EHNA and THNA) on purine metabolism in Sarcoma 180 cells have been determined. At concentrations of 10-80 microM [10- to 1000-fold greater than their Ki values with adenosine deaminase (ADA)], all isomers

We examined the antitumor effects of two antifolate inhibitors of thymidylate synthesis, N-(5-[N-(3, 4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino ]-2-theno yl-L-glutamic acid (D1694; Tomudex) and 1843U89 as well as a folate-based inhibitor of purine synthesis, 5,

The transcriptional control region of the Rouse sarcoma virus long terminal repeats (LTR) was shown to contain enhancer and promoter elements located within 200 base pairs upstream from the transcription initiation site [Cullen et al. (1985) Mol. Cell. Biol. 5, 438-447]. Deletion of these elements
