Abstract
Bacteria from the genus Mycobacterium include pathogens that cause serious diseases in humans and remain as difficult infectious agents to treat. Central to these challenges are the composition and organization of the mycobacterial cell envelope, which includes unique and complex glycans. Inositol is an essential metabolite for mycobacteria due to its presence in the structural core of the immunomodulatory cell envelope glycolipids phosphatidylinositol mannoside (PIM) and PIM-anchored lipomannan (LM) and lipoarabinomannan (LAM). Despite their importance to mycobacterial physiology and pathogenesis, many aspects of PIM, LM, and LAM construction and dynamics remain poorly understood. Recently, probes that allow metabolic labeling and detection of specific mycobacterial glycans have been developed to investigate cell envelope assembly and dynamics. However, these tools have been limited to peptidoglycan, arabinogalactan, and mycolic acid-containing glycolipids. Herein, we report the development of synthetic azido inositol (InoAz) analogues as probes that can metabolically label PIMs, LM, and LAM in intact mycobacteria. Additionally, we leverage an InoAz probe to discover an inositol importer and catabolic pathway in Mycobacterium smegmatis. We anticipate that in the future, InoAz probes, in combination with bioorthogonal chemistry, will provide a valuable tool for investigating PIM, LM, and LAM biosynthesis, transport, and dynamics in diverse mycobacterial organisms.

Abstract
We have carried out a structural exploration of (2S,4R,5R)-2-(bis(4-fluorophenyl)methyl)-5-((4-methoxybenzyl)amino)tetrahydro-2H-pyran-4-ol (D-473) to investigate the influence of various functional groups on its aromatic ring, the introduction of heterocyclic aromatic rings, and the alteration of the stereochemistry of functional group on the pyran ring. The novel compounds were tested for their affinities for the dopamine transporter (DAT), serotonin transporter (SERT), and norepinephrine transporter (NET) in the brain by measuring their potency in inhibiting monoamine neurotransmitter uptake. Our studies identified some of the most potent dopamine-norepinephrine reuptake inhibitors known to-date like D-528 and D-529. The studies also led to development of potent triple reuptake inhibitors such as compounds D-544 and D-595. A significant influence from the alteration of the stereochemistry of the hydroxyl group on the pyran ring of D-473 on transporters affinities was observed indicating stereospecific preference for interaction. The inhibitory profiles and structure-activity relationship of lead compounds were further corroborated by molecular docking studies at the primary binding sites of monoamine transporters. The nature of interactions found computationally correlated well with their affinities for the transporters.

Abstract
In the reaction of purines with ferrocenoyl chloride in dimethylformamide (DMF), a regioselective acylation occurred. The two products have been isolated and, according to detailed NMR analysis, identified as N7- and N9-ferrocenoylated isomers. In a more polar solvent, for example, in dimethylsulfoxide (DMSO), the two isomers interconvert to each other. The N7/N9 isomerization was followed by 1H NMR spectroscopy, until dynamic equilibrium was reached. Both kinetics and thermodynamics of the transacylation process are governed by a C6-substituent on the purine ring (R = NH2, Me, NHBz, OBz). The observed rate constant for the N7/N9-isomerization in the adenine system (R = NH2) is kobs = 0.3668 h-1, whereas the corresponding process in the C6-benzyloxypurine is 56 times slower. By use of density functional theory calculations and molecular dynamics simulations, several reaction pathways were considered and explored. Only the reaction mechanism involving DMSO as a nucleophilic reactant is in harmony with the experimental kinetic data. The calculated barrier (ΔG⧧ = 107.9 kJ/mol; at the M06L/6-311+G(d,p)/SDD level of theory) for this SN2-like reaction in the adenine system agrees well with the experimental value of 102.7 kJ/mol. No isomerization was detected in other organic solvents, for example, acetonitrile, N,N-dimethylformamide, or acetone, which indicated the exceptional nucleophilicity of DMSO. Our results raise a warning when treating or dissolving acylated purines in DMSO as they are prone to isomerization. We observed that the N7/N9-group transfer was specific not only for the organometallic moiety only, but for other acyl groups in purines as well. The relevance of this isomerization may be expected for a series of nucleobases and heterocyclic systems in general.

Abstract
Diphosphoinositol phosphates (PP-InsPs) are an evolutionarily ancient group of signalling molecules that are essential to cellular and organismal homeostasis. As the detailed mechanisms of PP-InsP signalling begin to emerge, synthetic analogues of PP-InsPs containing stabilised mimics of the labile diphosphate group can provide valuable investigational tools. We synthesised 5-PCF2Am-InsP5 (1), a novel fluorinated phosphonate analogue of 5-PP-InsP5, and obtained an X-ray crystal structure of 1 in complex with diphosphoinositol pentakisphosphate kinase 2 (PPIP5K2). 5-PCF2Am-InsP5 binds to the kinase domain of PPIP5K2 in a similar orientation to that of the natural substrate 5-PP-InsP5 and the PCF2Am structure can mimic many aspects of the diphosphate group in 5-PP-InsP5. We propose that 1, the structural and electronic properties of which are in some ways complementary to those of existing phosphonoacetate and methylenebisphosphonate analogues of 5-PP-InsP5, may be a useful addition to the expanding array of chemical tools for the investigation of signalling by PP-InsPs. The PCF2Am group may also deserve attention for wider application as a diphosphate mimic.
