Novel Acylthiol Compositions and Methods of Making and Using Them

Description of Technology: This invention provides a novel family of acylthiols and uses thereof. More specifically, this invention provides effective inhibitors of HIV that selectively target its highly conserved nucleocapsid protein (NCp7) by interacting with metal chelating structures of a zinc finger-containing protein. Because of the mutationally intolerant nature of NCp7, drug resistance is much less likely to occur with compounds attacking this target. In addition, these drugs should inactivate all types and strains of HIV and could also inactivate other retroviruses, since most retroviruses share one or two highly conserved zinc fingers that have the CCHC motif of the HIV Ncp7. Finally, this invention could be very useful for the large-scale practical synthesis of HIV inhibitors, because these compounds can be prepared by using inexpensive starting materials and facile reactions. Thus, it opens the possibility that an effective drug treatment for HIV could be made available to much larger populations. These thioesters may also be used as an active component in topical applications that serve as a barrier to HIV infection.

Novel Thioesters and Uses Thereof

Description of Technology: The human immunodeficiency virus (HIV) is the causative agent of acquired immunodeficiency syndrome (AIDS). Drug-resistance is a critical factor contributing to the gradual loss of clinical benefit to treatments for HIV infection. Accordingly, combination therapies have further evolved to address the mutating resistance of HIV. However, there has been great concern regarding the apparent growing resistance of HIV strains to current therapies.

The present invention provides for a novel family of thioesters and uses thereof. These thioesters are capable of inactivating viruses by a variety of mechanisms, particularly by complexing with metal ion-complexing zinc fingers. The invention further provides for methods for inactivating a virus, such as the human immunodeficiency virus (HIV), using these compounds, and thereby also inhibiting transmission of the virus.
