The development of a safe, effective, and affordable microbicide to prevent the sexual transmission of HIV combination is urgently needed. Our previous studies demonstrated that 3-hydroxyphthalic anhydride-modified chicken ovalbumin (HP-OVA) exhibited potent antiviral activity against a broad spectrum of HIV...

We recently demonstrated that both 3-hydroxyphthalic anhydride (HP)- and maleic anhydride-modified chicken ovalbumin (OVA) could effectively inhibit HIV-1 infection. But because OVA may cause allergy in some human subjects, here we replaced OVA with human serum albumin (HSA) in designing...

Chemical modification of the proteins bovine serum albumin, alpha-lactalbumin, beta-lactoglobulin and chicken lysozyme by 3-hydroxyphthalic anhydride (3-HP) yielded compounds which exerted antiviral activity in vitro as compared with the native unmodified proteins. Of the three enveloped viruses tested, human herpes...

To investigate the antiviral activity of 3-hydroxyphthalic anhydride-modified ovalbumin (HP-OVA) against herpes simplex virus 2 (HSV-2) in vitro. By chemical modification, ovalbumin (OVA) was treated with 3-hydroxyphthalic anhydride (HP) to prepare HP-OVA. The anti-HSV-2 activity against HSV-2 333 virus in...
