Research on antimetabolites of nucleic acid purines led to drugs for the treatment of acute leukemia (6-mercaptopurine and thioguanine), gout and hyperuricemia (allopurinol), and herpesvirus infections (acyclovir), and for the prevention of organ transplant rejection (azathioprine).
A series of bifunctional alkylators were tested against the genotypically and phenotypically heterogeneous continuous human medulloblastoma cell lines, TE-671, Daoy, and D283 Med in vitro and against TE-671 and Daoy growing as s.c. and intracranial xenografts in athymic mice. Drugs tested included melphalan, cyclophosphamide, iphosphamide,… (More)
A guanine derivative with an acyclic side chain, 2-hydroxyethoxymethyl, at position 9 has potent antiviral activity [dose for 50% inhibition (ED(50)) = 0.1 muM] against herpes simplex virus type 1. This acyclic nucleoside analog, termed acycloguanosine, is converted to a monophosphate by a virus-specified pyrimidine deoxynucleoside (thymidine) kinase and is… (More)
Acyclovir, 9-(2-hydroxyethoxymethyl)guanine, is an acyclic nucleoside analogue which has a high activity and selectivity for herpes viruses, particularly herpes simplex viruses types 1 and 2 and varicella zoster virus. This selectivity is due to the initial activation of the drug by phosphorylation by a herpes virus-specified thymidine kinase. Normal… (More)
The ribonucleotide reductase induced by herpes simplex virus type 1 (HSV-1) was purified in high yield from serum-starved baby hamster kidney (BHK-21) cells infected with HSV-1 (strain H-29). The enzyme preparation was essentially free of both eucaryotic ribonucleotide reductase and contaminating enzymes that could cause significant depletion of substrates.… (More)

Of a series of nucleoside analogues synthesised, 9-(2-hydroxyethoxymethyl) guanine was found to have marked antiviral activity in animal models of herpes virus infections, associated with very low toxicity.
