LMT-28 is an experimental drug which was the first molecule discovered that acts as an antagonist of IL6R, the receptor for Interleukin-6, and so blocks its activity in the body. Interleukin-6 is a cytokine signalling molecule which plays a key role in inflammation, so blocking IL6R is useful for alleviating a number of disease processes in which inflammation plays a part. Previously it has only been possible to block cytokine activity using biologics such as targeted antibodies which have various disadvantages, so the development of small molecule inhibitors is a considerable advance. LMT-28 is of relatively low potency and is unlikely to be developed as a medicine, but is useful for pharmaceutical research into the processes mediated by IL6R, [1] [2] [3] [4] [5] [6] [7] and as a successful proof of concept it makes it likely that more potent small molecule antagonists for IL6R and other interleukin receptors will be developed in future.
