New drugs against visceral leishmaniasis with mechanisms of action differing from existing treatments and with adequate cost, stability, and properties are urgently needed. No antitubulin drug is currently in the clinic against Leishmania infantum, the causative agent of visceral leishmaniasis in the Mediterranean area. We have designed and synthesized a focused library of 350 compounds against the Leishmania tubulin based on the structure-activity relationship (SAR) and sequence differences between host and parasite. The compounds synthesized are accessible, stable, and appropriately soluble in water. We assayed the library against Leishmania promastigotes, axenic, and intracellular amastigotes and found 0, 8, and 16 active compounds, respectively, with a high success rate against intracellular amastigotes of over 10%, not including the cytotoxic compounds. Five compounds have a similar or better potency than the clinically used miltefosine. 14 compounds showed a host-dependent mechanism of action that might be advantageous as it may render them less susceptible to the development of drug resistance. The active compounds cluster in five chemical classes that provide structure-activity relationships for further hit improvement and facilitate series development. Molecular docking is consistent with the proposed mechanism of action, supported by the observed structure-activity relationships, and suggests a potential extension to other Leishmania species due to sequence similarities. A new family of diarylsulfonamides designed against the parasite tubulins is active against Leishmania infantum and represents a new class of potential drugs with favorable cost, stability, and aqueous solubility for the treatment of visceral leishmaniasis (VL). These results could be extended to other clinically relevant species of Leishmania spp.

Monoacylglycerol lipase (MAGL) is the enzyme degrading the endocannabinoid 2-arachidonoylglycerol, and it is involved in several physiological and pathological processes. The therapeutic potential of MAGL is linked to several diseases, including cancer. The development of MAGL inhibitors has been greatly limited by the side effects associated with the prolonged MAGL inactivation. Importantly, it could be preferable to use reversible MAGL inhibitors in vivo, but nowadays only few reversible compounds have been developed. In the present study, structural optimization of a previously developed class of MAGL inhibitors led to the identification of compound 23, which proved to be a very potent reversible MAGL inhibitor (IC50 = 80 nM), selective for MAGL over the other main components of the endocannabinoid system, endowed of a promising antiproliferative activity in a series of cancer cell lines and able to block MAGL both in cell-based as well as in vivo assays.

Disclosed are isolated, unnatural polypeptides containing cyclically-constrained β-amino acid residues and cyclically-constrained γ-amino acid residues. The compounds are unnatural and because they contain rotationally constrained residues that are not amenable to enzymatic degradation, the compounds are useful to probe protein-protein and other large molecule interactions.

Page 204-208, (2010/02/05)
The present invention provides compounds having formula (I): wherein R’, R0, R1, X1, R2, R3, R3’, X2, X3, and R4 are as defined herein, and pharmaceuticals compositions thereof. The present invention also provides methods of inhibiting proteases, more specially aspartyl proteases. In certain embodiments, compounds inhibit BACE (β-site APP-cleaving enzyme), and thus are useful in the treatment or prevention of a disease characterized by β-amyloid deposits in the brain (including, but not limited to, Alzheimer’s Disease). The present invention also provides methods for preparing compounds of the invention.
2,5-dimethylpyrrole protection facilitates copper(I)-mediated methoxylations of aryl iodides in the presence of anilines

Converting iodoanilines to the corresponding 2,5-dimethylpyrroles was found to facilitate CuCI-mediated methoxide substitution. Examples with ortho-, meta-, or para-relationships between the iodide and aniline are presented. Several other aniline blocking groups were investigated and found not to be successful in this sequence.
