An adamantyl-caffeoyl-anilide exhibits broad-spectrum antibacterial activity by inhibiting FtsZ assembly and Z-ring formation.

Several harmful bacteria have evolved resistance to conventional antibiotics due to their extensive usage. FtsZ, a principal bacterial cell division protein, is considered as an important drug target to combat resistance. We identified a caffeoyl anilide derivative, (E)-N-(4-(3-(3,4-dihydroxyphenyl)acryloyl)phenyl)-1-adamantylamide (compound 11) as a new antimicrobial agent targeting FtsZ.

Anti-HIV activity of Indian medicinal plants.

Acquired immunodeficiency syndrome patients face great socio-economic difficulties in obtaining treatment. There is an urgent need for new, safe, and cheap anti-HIV agents. Traditional medicinal plants are a valuable source of novel anti-HIV agents and may offer alternatives to expensive medicines in future.

Synthesis of 9-substituted derivatives of berberine as anti-HIV agents.

Naturally occurring protoberberine alkaloids, berberine and berberrubine along with 9-substituted derivatives of berberine were assessed for the anti-human immunodeficiency virus (HIV) activity. Berberine was found to be the most active compound with an EC(50) of 0.13 μM against HIV-1 NL4.

Design and synthesis of caffeoyl-anilides as portmanteau inhibitors of HIV-1 integrase and CCR5.

Designing multi-functional ligands is a recent strategy by which multiple targets can be inhibited by a single entity. A series of caffeoyl-anilide compounds based on structures of various integrase and CCR-5 inhibitors have been designed and synthesized as anti-HIV agents in the present study. Most of the compounds exhibited potent anti-HIV activity at micromolar concentration in CEM-GFP CD4+ T cells infected with HIV-1NL4.

Anti-HIV diterpenes from Coleus forskohlii.

Various extracts of the aerial parts of Coleus forskohlii (Labiatae) were prepared and evaluated at their non cytotoxic concentration against HIV-1 NL4-3. Chloroform, ethyl acetate and n-butanol extracts showed 45.6, 66.
