New drugs are urgently needed for the treatment of tropical parasitic diseases such as leishmaniasis and human African trypanosomiasis (HAT). This work involved a high-throughput screen of a focussed kinase set of ?3400 compounds to identify potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. The aim of this study is to provide chemical validation that Leishmania CRK3-CYC6 is a drug target. Eight hit series were identified, of which four were followed up. The optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin dependent kinase CDK2. Selective at last: [1,2,4]Triazolo[1,5-a]pyridines, aminopyrazoles, and disubstituted ureas were explored as potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. Optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin-dependent kinase CDK2.

The synthesis of 2,4,6-triiodoisophthalamides substituted by a lactam moiety is described. A tandem ring opening-ring closure methodology consisting of a regiospecific ether cleavage of the tetrahydrofuroanilide 14b, followed by lactamization to alpha-oxygenated anilides 15b or 16b, gave alpha-O-functionalized-delta-valerolactams 12b or 13b, respectively. This approach is also compatible with the presence of ester and carbonyl chloride functions on the triiodophenyl moiety. A general synthesis of lactams 34-39 was also achieved. Further chemical modifications led to water soluble unsubstituted-lactams (34d, 35d, 37d) and alpha-hydroxyl-lactams [42(d,e), 13(d,e) and 43d] that are of interest as X-ray contrast agents.

A novel fluorescent sensor (AQTF1) based on the N-(quinolin-8-yl) tetrahydrofuran-2-carboxamide was designed and synthesized. This new sensor demonstrated high selectivity for the Zn2+ without the interference from Cd2+. The detection limit of this probe was calculated to be 10.8 nM for Zn2+. The in situ prepared AQTF1-Zn2+ complex was used for detection of H2PO4? and displayed good selectivity from the common anions. Furthermore, the AQTF1 displayed good ratiometric response for the relay recognition for Zn2+ and H2PO4?.

A potent class of indolinyl-thiazole based inhibitors of cellular lipid uptake mediated by scavenger receptor, class B, type I (SR-BI) was identified via a high-throughput screen of the National Institutes of Health Molecular Libraries Small Molecule Repository (NIH MLSMR) in an assay measuring the uptake of the fluorescent lipid DiI from HDL particles. This class of compounds is represented by ML278 (17-11), a potent (average IC50 = 6 nM) and reversible inhibitor of lipid uptake via SR-BI. ML278 is a plasma-stable, noncytotoxic probe that exhibits moderate metabolic stability, thus displaying improved properties for in vitro and in vivo studies. Strikingly, ML278 and previously described inhibitors of lipid transport share the property of increasing the binding of HDL to SR-BI, rather than blocking it, suggesting there may be similarities in their mechanisms of action.

The crystal structure of the resting state of cytochrome P450 cam (CYP101), a heme thiolate protein, shows a cluster of six water molecules in the substrate binding pocket, one of which is coordinating to iron(III) as sixth ligand. The resting state is low-spin and changes to high-spin when substrate camphor binds and H2O is removed. In contrast to the protein, previously synthesised enzyme models such as H 2O-FeIII(porph)(ArS-) were shown to be purely high-spin. Iron(S-)porphyrins with different distal sites mimicking proposed remote effects have been prepared and studied by cw-EPR. The results indicate that the low-spin of the resting state of P450cam is due to the fact that the water molecule coordinating to iron has an OH –like character because of hydrogen bonding and polarisation of the water cluster, respectively.

DNA topoisomerases are well-validated targets in micro-organisms. DNA gyraseB is one of the most important enzymes among them as per their clinical importance. In earlier study, a novel lead 4-((4-(furan-2-carboxamido)phenyl)amino)-4-oxobutanoic acid was identified as inhibitor against DNA gyraseB with an IC50 of 12.88 ± 1.39 mum. Subsequently, analogues of this lead were developed and evaluated through in vitro assays and in vivo studies. Among the 24 analogues, compound 22 was found to be the top hit with an improved DNA gyraseB activity of 5.35 ± 0.61 mum, and the binding affinity of this compound was further ascertained biophysically through differential scanning fluorimetry. The most potent ligand did not show any signs of cardiotoxicity in zebra fish ether-ago-go-related gene, ascertaining the safety profile of this series a breakthrough among the previously reported cardiotoxic gyraseB inhibitors.

As part of an effort to identify novel backups for previously reported pyrazole-based coagulation Factor Xa inhibitors, the pyrazole 5-carboxamide moiety was replaced by 3-(sulfonylamino)-2-piperidone. This led to the identification of a structurally diverse chemotype that was further optimized to incorporate neutral or weakly basic aryl and heteroaryl P1 groups while maintaining good potency versus Factor Xa. Substitution at the sulfonamide nitrogen provided further improvements in potency and as did introduction of alternate P4 moieties.
