Supramolecular adducts of native and permethylated beta-cyclodextrins with (2,2?-dipyridylamine)chlorido(1,4,7-trithiacyclononane)ruthenium(II) chloride: Solid-state and biological activity studies

The complex [([9]aneS3)RuII(dipa)Cl]Cl (1, where dipa = 2,2?-dipyridylamine) was included into native beta-cyclodextrin (beta-CD) and permethylated beta-CD (TRIMEB) by co-dissolution followed by solvent removal. Two adducts were obtained with a 1:1 host:guest stoichiometry. Solid-state studies of the guest comprised collecting the single-crystal structure of its 3.5 hydrate form and also powder diffraction on the remaining bulk material, showing it is isotypical with the harvested crystal for X-ray analysis. Solid-state studies of the cyclodextrin adducts were carried out by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), 13C{1H} CP/MAS NMR and FTIR spectroscopies. Biological studies on 1 and its adducts comprised the evaluation of the shift caused by 1 on the melting temperature of DNA (DeltaT m), as well as the evaluation of cytotoxicity by the MTT assay on the osteosarcoma MG-63 cell line.

Exploring NAG-thiazoline and its derivatives as inhibitors of chitinolytic beta-acetylglucosaminidases

NAG-thiazoline (NGT) and its derivatives are well-known inhibitors against most beta-acetylglucosaminidases (beta-GlcNAcases) except for insect and bacterial chitinolytic beta-GlcNAcases, including the molting-indispensable OfHex1 from the insect Ostrinia furnacalis. Here, we report the co-crystal structure of OfHex1 in complex with NGT. This structure reveals a large active pocket in OfHex1 that may account for the poor inhibitory activity of NGT. To test this hypothesis, a bulky substituent was designed and synthesized on the thiazoline ring of NGT. The resulting compound (NMAGT) was determined to be a submicromolar inhibitor of OfHex1 with a Ki value of 0.13 muM, which is 600-fold lower than Ki value of NGT. Molecular dynamics simulation analysis supported the good fit of NMAGT to the active pocket.

Emission studies of hetero-bischelated iridium(III)-diimine complexes

Two mixed-ligand complexes, cis-[Ir(bipy)(HDPA)Cl2]Cl and cis-[Ir(phen)(HDPA)Cl2]Cl (where bipy = 2,2?-bipyridine, phen = 1,10-phenanthroline, and HDPA = 2,2?-dipyridylamine), have been synthesized and characterized. Both complexes show spin-allowed pi-pi* bands in the UV region. Besides, spin-allowed and spin-forbidden charge transfer bands are also observed in the vicinity of 24.8 and 19.5 kK, respectively. The magnitude of the polarization, P, in the excitation polarization spectra obtained for the two complexes indicate that both luminophores behave as linear oscillator corresponding to the symmetry lower than C2upsilon of the two complexes. The emission spectra of both cis-[Ir(bipy)(HDPA)Cl2]+ in neutral and cis-[Ir(phen)(HDPA)Cl2]+ in slightly acidified EtOH-MeOH solvent (4:1 v/v) at 77 K, exhibit 3MLCT phosphorescence at 16-22 kK with lifetimes near 18 mus and a single vibration progression of 1240 and 1300 cm-1, respectively. The property that the emission energy becomes smaller while the polarity of solvent increases is consistent with the orbital nature of 3MLCT state. The emission energies of both complexes are nearly constant in acidic EtOH-MeOH solvent and are 3.1-3.3 kK smaller in basic solvent than that in the neutral one. The emissions of both complexes in the basic case are assigned as 3MLCT emission caused by the complexes of deprotonated form, cis-Ir(bipy)(DPA)Cl2 and cis-Ir(phen)(DPA)Cl2, with lifetimes of approximately 19 mus.

Synthesis, chemical characterization and antimicrobial activity of new acylhydrazones derived from carbohydrates

A new series of glycosylated acylhydrazones was synthesized and all the chemical structures were confirmed by High Resolution Mass Spectrometry (HRMS), 1H and 13C Nuclear Magnetic Resonance (1H-NMR; 13C-NMR) and Fourier Transform Infrared (FTIR) spectroscopy methods. The mass accuracy between the calculated and found values observed in HRMS analyses were near or lower than 5 ppm, which are acceptable for proposing a molecular formula using this technique. All of the synthesized compounds were screened for their antibacterial, antifungal and antiviral activities. Five compounds (12, 13, 14, 16 and 19) exerted a modest antifungal activity against the strains evaluated. Derivative 14 showed fungicidal activity against Candida glabrata at 173.8 muM and saccharide unit contributed to the increase of the antifungal potential against this strain. New chemical manipulation of derivative 14 can make it possible to obtain new potentially antimicrobial agents.

A closer look at the bromine-lithium exchange with tert-butyllithium in an aryl sulfonamide synthesis

A practical protocol for the one-pot synthesis of various aryl sulfonamides, notably of pyridine-core-substituted 7-azaindolyl sulfonamides, is described. A key step is the well-known bromine-lithium exchange reaction of an aryl bromide with tert-butyllithium (t-BuLi). Differing from the common practice to use 2 or more equiv of organolithium, the exact amount of t-BuLi needed for a sufficient exchange reaction is determined for each aryl bromide in a GC-MS-assisted experiment.

Iminosugar glycoconjugates

The iminosugar conjugates according to the invention are N-alkylated 1,5-dideoxy-1,5-iminohexitol or 1,5-dideoxy-1,5-iminopentitol derivatives. The iminosugar component can be, for example, D-gluco-, L-ido-, D-galacto-, D-manno-, 2-acetamido-2-deoxy-D-gluco- or xylo-configuration. The N-substituent is a protected L-alpha-aminoacid derivative, showing L-lysine-like structural features. The linkage between the carbohydrate and the peptide component is not via the usual glycosidic position, but shows structural features of a very stable tertiary amine. Thus the linkage is very stable. These new compounds are synthesised by using catalytic intramolecular reductive amination of dicarbonyl sugars with partially protected amino acids. The process of intramolecular reductive amination itself is carried out using Pearlman’s catalyst (Pd(OH)2/C) and H2 at ambient pressure and room temperature. The resulting accessible class of iminosugar conjugate compounds is represented by the general structure shown in Figure 4(c). The alkyl chain length parameter n can be freely chosen from n=0 upwards. Preferably n is between 0 and 10, and more preferably n is 2, 3, or 4. Residue R1 can be chosen from H, OH, or NHAc, with Ac being Acetyl. R2 can be H, OH, or NHAc. R3, R4, R5, R6 can be H or OH. R7 and R8 can be H, CH2OH CH3, COQH, or COOR with R being Alkyl or Aryl. R9 and R10 can be chosen from H, NH2, NHR, with R being a protective group, an amino acid, a peptide, or a protein. R11 can be OH, O-Alkyl, O-Aryl, NH2, N-Alkyl, N-Aryl, amino acid or peptide, connected via an amide bond.

Histidine-Specific Peptide Modification via Visible-Light-Promoted C-H Alkylation

Histidine (His) carries a unique heteroaromatic imidazole side chain and plays irreplaceable functional roles in peptides and proteins. Existing strategies for site-selective histidine modification predominantly rely on the N-substitution reactions of the moderately nucleophilic imidazole group, which inherently suffers from the interferences from lysine and cysteine residues. Chemoselective modification of histidine remains one of the most difficult challenges in peptide chemistry. Herein, we report peptide modification via radical-mediated chemoselective C-H alkylation of histidine using C4-alkyl-1,4-dihydropyridine (DHP) reagents under visible-light-promoted conditions. The method exploits the electrophilic reactivity of the imidazole ring via a Minisci-type reaction pathway. This method exhibits an exceptionally broad scope for both peptides and DHP alkylation reagents. Its utility has been demonstrated in a series of important peptide drugs, complex natural products, and a small protein. Distinct from N-substitution reactions, the unsubstituted nitrogen groups of the modified imidazole ring are conserved in the C-H alkylated products.
