With the rise in resistance to antibiotics such as methicillin, there is a need for new drugs. The invention provides small molecules that inhibit cellular drug targets such as UPPS and FPPS by interacting with binding pockets, thereby preventing enzyme function. Compounds described herein are also active against Staphylococcus aureus (MIC90 ~0.25 µg/mL), can potently synergize with methicillin (fractional inhibitory concentration index = 0.25), and are protective in a mouse infection model. The invention therefore provides numerous compounds for anti-bacterial treatments and for restoring sensitivity to drugs such as methicillin, using combination therapies.

Ginkgolic acid (C13:0) (GA), isolated from Ginkgo biloba, is a potential therapeutic agent for type 2 diabetes. A series of GA analogs were designed and synthesized for the evaluation of their structure–activityrelationship with respect to their antidiabetic effects. Unlike GA, the synthetic analog 1e exhibited improved inhibitory activity against PTPN9 and significantly stimulated glucose uptake

A series of 6-oxa isosteres of anacardic acids (6-higher alkkyl/alkenyl-2-hydroxybenzoic acids) was synthesised and several members were discovered to be among the most potent inhibitors (IC50 values less than or equal to 5 mu M) of the bacterial two-component regulatory systems, KinA/SpoOF and NRII/NRI, reported to date. The Gram-positive antibacterial activity in selected strains is also presented. (C) 1999 Elsevier Science Ltd. All rights reserved.
