# ANTITUMOR AND ANTIVIRAL NUCLEOSIDE ANALOGUES

> **NIH NIH R01** · BARBARA ANN KARMANOS CANCER INSTITUTE · 1989 · $192,868

## Abstract

Novel nucleoside analogous will be prepared and studied as
potential antitumor and antiviral agents.  These compounds will
include:  (i) "Hydroxycarbocyclic" analogous of cytidine, 3-
deazaadenosine, vidarabine and cytarabine, (ii) unsaturated
carbocyclic nucleoside analogues related to neplanocin A including
L-homocysteinylneplanocin A, (iii) phosphonate derivatives of open-
chain unsaturated nucleoside analogues and (iv) analogues of
adenosine deaminase inhibitor EHNA.  All compounds will be obtained
by chemical synthesis.  Analogues (i) and (ii) will be obtained
either in racemic form or optically pure by a new chemico-enzymatic
approach.

Antitumor activity and mechanism of action of the active analogues
will be studied in vitro and in vivo in murine leukemia L 1210,
P388, and sixteen solid tumor systems.  Particular attention will
be paid to:  (i) inhibition of macromolecular synthesis, (ii)
reversal studies with specific metabolites, (iii) alterations in
nucleotide pool sizes, and (iv) effects on RNA maturation.
Antiviral activity of the obtained analogues will also be
investigated.

Suitable analogues will be studied as substrates (inhibitors) of
adenosine deaminase and adenosine homocysteine hydrolase.
