英文摘要
This proposal describes a comprehensive program involving
synthetic, mechanistic, biological, and computer modeling studies
directed at the elucidation of the mode of action of demonstrated and
of potential cancer chemotherapeutic agents, at the rational design
and development of new classes of antitumor agents, and at the
development of fundamentally new methodology and strategies for the
synthesis of such agents. Five projects are proposed for
investigation. A major continuation study will be directed at
neocarzinostatin chromophore, the recently identified, structurally
unprecedented, biologically active subunit of neocarzinostatin (NCS),
a drug used in human cancer chemotherapy. Efforts will focus on
determining the molecular basis for the antitumor activity of NCS, on
establishing the basis for its DNA cleavage selectivity, on the
utilization of this information in the rational design of new
antitumor agents, and on the synthesis of simplified analogues and
biological probes needed in support of these studies. A second major
project is focussed on dynemicin A (Dyn A), an exciting new
chemotherapeutic lead exhibiting significant in vitro and in vivo
antitumor activity. Attention will be directed at the mechanism of
activation of Dyn A, at the rational design and development of new Dyn
A analogues, at the structural basis for its DNA lesion selectivity,
and at an examination of a potentially biomimetic approach to its
unprecedented structure. A third project is directed at the
development of fundamentally new classes of DNA-cleaving agents and
potential cancer chemotherapeutics that are designed to function by
the transition metal, photochemical, and torsional induction of
diradical formation. A fourth major effort is focussed on taxol, a
compound whose recent, impressive clinical performance is likely to
result in its imminent approval for use in cancer chemotherapy. This
study is directed at the development of practical approaches to taxol
analogues and at the elucidation of the structural requirements for
taxol's activity. A final project entails completion of studies on
the synthesis of aplysiatoxin. Overall, this research program is
expected to be of significant value in chemistry, biology, and
medicine.
