Flufenamic acid, a non-steroidal anti-inflammatory drug, is known to potentlyinhibit AKR1C3 in a non-selective manner as COX off-target effects are also observed. To diminish off-target effects, we have applied a scaffoldhopping strategy replacing the benzoic acid moiety of flufenamic acid with an acidic hydroxyazolecarbonylic scaffold. In particular, differently N-substituted hydroxylated triazoles

Compound 4, derived from IMD-0354, blocks the canonical NF-κB pathway although it is inactive on the IKKβ enzyme.
化合物4,源自IMD-0354,尽管对IKKβ酶无效,但可以阻断经典NF-κB途径。

Modification of the acyl moiety in the CCR5 lead molecule 2 led to identification of several new classes of CCR5 antagonists. Antiviral activity and pharmacokinetic properties of the synthesized compounds were evaluated. Structure-activity relationship (SAR) derived from these studies further guided the optimization efforts, ultimately leading to the discovery of 36 with an acceptable drug-like profile.
