It is thought that the mechanism of action of thiamine on endothelial cells is related to a reduction in intracellular protein glycation by redirecting the glycolytic flux. Thiamine is mainly the transport form of the vitamin, while the active forms are phosphorylated thiamine derivatives. There are five known natural thiamine phosphate derivatives: thiamine monophosphate (ThMP), thiamine diphosphate (ThDP), also sometimes called thiamine pyrophosphate (TPP), thiamine triphosphate (ThTP), and the recently discovered adenosine thiamine triphosphate (AThTP), and adenosine thiamine diphosphate. Each derivative has unique functions, however, most are involved as coenzymes.

The present invention relates to new Phosphodiesterase type 4 (PDE4) inhibitors of the formula (1) for treatment of asthma: Ar is a substituted or unsubstituted aryl, substituted or unsubstituted arylalkyl, substituted or unsubstituted heterocyclic ring or substituted or unsubstituted heteroaryl ring; each occurrence of L is O, S or NR3; X and A are independently -CRaRb -, -CRa-, -C(=B)-, O, S(O)m, N or NR3; each occurrence of m is 0, 1, or 2; n is 0-4; p is 0-2; Y is -C(=B)C(=D)NR4 or -C(=B)NR4 B is O, S or NRa; D is O, S or NRa; The other substituents are defined in the claims.
The invention provides inhibitors of a sterol C14-demethylase, a new series of 4- aminopyridyl-based lead inhibitors targeting Trypanosoma cruzi CYP51 (TcCYP51) developed using structure-based drug design as well as structure -property relationship (SPR) analyses. The screening hit starting point, LP 10 (KD < 42 nM; EC50 of 0.65 μΜ), has been optimized to give the potential leads that have low nanomolar binding affinity to TcCYP51 and significant activity against T. cruzi amastigotes cultured in human myoblasts. Many of the optimized compounds have improved microsome stability, and most are selective against the T. cruzi CYP51 relative to human CYPs 1A2, 2D6 and 3A4 (<50% inhibition at 1 μΜ). A rationale for the improvement of microsome stability and selectivity of inhibitors against human metabolic CYP enzymes is presented. In addition, the binding mode of several compounds of the invention with the T. brucei CYP51 (TbCYP51) ortholog has been characterized by x-ray structure analysis. Orally active compounds and their cyclodextrin complexes have been shown to be effective against Chagas-infected mice.
