HSV-1 gD Inhibitors

The class of HSV-1 gD inhibitors comprises a diverse range of chemicals that directly or indirectly target the viral protein gD, a critical component of the herpes simplex virus type 1 (HSV-1). One approach involves direct inhibition of viral replication, exemplified by nucleoside analogs like Cidofovir and Acyclovir. These compounds act as inhibitors of HSV-1 DNA polymerase, disrupting viral DNA synthesis and ultimately reducing the production of gD. This highlights the efficacy of targeting viral components to attenuate the expression and function of specific viral proteins, such as gD. Additionally, indirect inhibitors like BX795 and BAY-2402234 exemplify a strategic approach by targeting host cellular processes. BX795 disrupts the STING-mediated antiviral response, indirectly impacting gD expression by modulating interferon pathways. On the other hand, BAY-2402234, a USP7 inhibitor, influences gD by disrupting the deubiquitination of host factors, emphasizing the ability of targeting host cellular processes to modulate viral protein activity. These examples showcase the versatility of inhibitors within this class, providing multiple avenues for intervention.

Furthermore, metabolic inhibitors such as 2-Deoxy-D-glucose highlight the ability to alter cellular energy production to impact viral replication and subsequently inhibit gD expression. Similarly, signaling pathway inhibitors like SP600125 and Ruxolitinib demonstrate the importance of host cell signaling cascades, offering indirect means to regulate gD expression. This chemical class's diversity underscores the complexity of host-virus interactions and provides a rich landscape for investigating antiviral strategies targeting HSV-1 gD.
