to anyone in the pharmaceutical industry, and you'll soon discover
that genetics is the biggest thing to hit drug research since
a penicillin mold floated into Alexander Fleming's pert dish.
Sure, scientists have long known genes play a role in almost every
ailment from Alzheimer's to yellow fever. But it is only in the
past few years that they've learned how to use that information
to identify a multitude of new targets and pathways for drug design.

discovery [Editorial
overview]. Current Opinion in Biotechnology. 9:559-560.
Abstract: There is a tendency now that genome sequencing and gene
expression analysis can be done on a massively parallel scale
to stop thinking about how to do hypothesis testing experiments.
In the not so good old days (BC...before cloning), it might have
taken weeks to prepare the reagents to do the experiments. Plenty
of time then to design them properly. In the good old days when
recombinant DNA ruled the world, quite often the experiments were
rapid (e.g. selecting recombinant clones) that if for some reason
the wrong clones were obtained it was relatively easy to go back
and get the right ones. Nowadays it is easy to generate enormous
amounts of genetic and genomic data, all to often with insufficient
thought to having a good way to find out what all the data mean.
The genetics of common complex diseases is apparently just like
Mendelian genetics, only more complex and of course ''just turn
the functional genomics handle and the functions of all unknown
genes will be revealed.''

Abstract: Improvements in homology search methodology and functional

The experimental methods needed for investigation of gene function
and expression in a variety of model systems of infection continue
to develop. The identification of surface-exposed microbial structures
and their conservation in natural populations of pathogenic species
offers prospects for developing novel vaccines. A major challenge
is the development of efficient screening methods to select the
most promising candidates, such as immunisation with DNA.

Burt. 1996. Structural Mechanisms of HIV Drug Resistance.
Annual Review of Pharmacology and Toxicology, 36: 545-571,
Abstract: Antiviral therapy for AIDS has focused on the discovery
and design of inhibitors for two main enzyme targets of the human
immunodeficiency virus type 1 (HIV)--reverse transcriptase (RT)
and protease (PR). Despite several classes of promising new anti-HIV
agents, the clinical emergence of drug-resistant variants of HIV
has severely limited the long-term effectiveness of these drugs.
Genetic analysis of resistant virus has identified a number of
critical mutations in the RT and PR genes. Structural analysis
of inhibitor-enzyme complexes and mutational modeling studies
are leading to a better understanding of how these drug-resistance
mutations exert their effects at a structural level. These insights
have implications for the design of new drugs and therapeutic
strategies to combat drug resistance to AIDS.

1998. Inhibitors of HIV-1 Protease: A Major
Success of Structure-Assisted Drug Design Annu. Rev. Biophys.
Biomol. Struct. 27:249-284.
Abstract: Retroviral protease (PR) from the human immunodeficiency
virus type 1 (HIV-1) was identified over a decade ago as a potential
target for structure-based drug design. This effort was very successful.
Four drugs are already approved, and others are undergoing clinical
trials. The techniques utilized in this remarkable example of
structure-assisted drug design included crystallography, NMR,
computational studies, and advanced chemical synthesis. The development
of these drugs is discussed in detail. Other approaches to designing
HIV-1 PR inhibitors, based on the concepts of symmetry and on
the replacement of a water molecule that had been found tetrahedrally
coordinated
between the enzyme and the inhibitors, are also discussed. The
emergence of drug-induced mutations of HIV-1 PR leads to rapid
loss of potency of the existing drugs and to the need to continue
the development process. The structural basis of drug resistance
and the ways of overcoming this phenomenon are mentioned.

peptidomimetic inhibitors
of HIV-1 protease. PNAS. 96(4): 1369-1374.
Abstract: We have developed a coevolutionary method for the computational
design of HIV-1 protease inhibitors selected for their ability
to retain efficacy in the face of protease mutation. For HIV-1
protease, typical drug design techniques are shown to be ineffective
for the design of resistance-evading inhibitors: An inhibitor
that is a direct analogue of one of the natural substrates will
be susceptible to resistance mutation, as will inhibitors designed
to fill the active site of the wild-type or a mutant enzyme. Two
design principles are demonstrated: (i) For enzymes with broad
substrate specificity, such as HIV-1 protease, resistance-evading
inhibitors are best designed against the immutable properties
of the active site the properties that must be conserved in any
mutant protease to retain the ability to bind and cleave all of
the native substrates. (ii) Robust resistance-evading inhibitors
can be designed by optimizing activity simultaneously against
a large set of mutant enzymes, incorporating as much of the mutational
space as possible.

257(5073):1078
Abstract: Most drugs have been discovered in random screens or
by exploiting information about macromolecular receptors. One
source of this information is in the structures of critical proteins
and nucleic acids. The structure-based approach to design
couples this information with specialized computer programs to
propose novel
enzyme inhibitors and other therapeutic agents. Iterated design
cycles have
produced compounds now in clinical trials. The combination of
molecular structure
determination and computation is emerging as an important tool
for drug
development. These ideas will be applied to acquired immunodeficiency
syndrome
(AIDS) and bacterial drug resistance.

Abstract: HIV drugs have had some success in reducing the number
of deaths
associated with AIDS. However, researchers revealed at the 12th
World AIDS
Conference in Geneva, Switzerland, that the HIV virus has learned
to resist the drug therapies. Protease inhibitors were thought
to be a way to treat the disease as a chronic disease as opposed
to a fatal one. The protease inhibitors also caused abnormal fat
deposits and high blood sugar levels.

Abstract: Merck and Abbott developed the protease inhibitors ritonavir

the amount of HIV in most infected people to levels that are not

and political strategies are examined.

saquinavir, indinavir and ritonavir, keep HIV from reproducing
after it eventually gets by the AZT.

Broder, Samuel; Hiroaki Mitsuya;
Robert Yarchoan. 1990. Molecular targets for AIDS therapy.
Science. 249(4976): 1533
Abstract: The development of antiretroviral therapy against acquired
immunodeficiency syndrome (AIDS) has been an intense research
effort since the discovery of the causative agent, human immunodeficiency
virus (HIV). A large array of drugs and biologic substances can
inhibit HIV replication in vitro. Nucleoside analogs - particularly
those belonging to the dideoxynucleoside family - can inhibit
reverse transcriptase after anabolic phosphorylation. 3'-Azido-2',3'-dideoxythymidine
(AZT) was the first such drug tested in individuals with AIDS,
and considerable knowledge of structure-activity relations has
emerged for this class of drugs. However, virtually every step
in the replication of HIV could serve as a target for a new therapeutic
intervention. In the future, non-nucleoside-type drugs will likely
become more important in the experimental therapy of AIDS, and
antiretroviral therapy will exert major effects against the morbidity
and mortality caused by HIV.
Palca, Joseph. 1990. Shooting at
a new HIV target. Science. 247(4941): 410
Abstract: Two teams of researchers, one at Smith Kline and French
Laboratories, the other at Upjohn Company, have discovered compounds
which prevent the AIDS virus, HIV, from reproducing itself. The
compounds work by interfering with a protein-degrading enzyme
which the virus requires to reproduce. This enzyme, called an
aspartic proteinase, resembles the human enzyme renin, which gave
researchers a head start in understanding its structure and function
and in developing compounds to block it. In tissue culture, HIV-infected
cells continue to produce virus in the presence of the enzyme
inhibitors, but the new virus is incapable of reproduction. The
enzyme inhibitors have not yet been tested in patients; the step
to patients is a large one. Proteinases are common in the body,
and if it turns out that
the HIV-protease inhibitor also inhibits an enzyme required for
normal body
processes, the treatment might be as bad as the disease. Researchers
point out that even though taking a tissue culture phenomenon
and turning it into a drug is a difficult step to take, it is
a necessary one in the development of new anti-HIV drugs.
