Enhanced efficacy of 7-hydroxy-3-methoxycadalene via glycosylation in in vivo xenograft study

7-Hydroxy-3-methoxycadalene, isolated from Zelkova serrata Makino, was confirmed as a biologically active natural compound. In this study, the efficacy of cadalene as an anticancer agent was tested. In order to address the poor physicochemical properties of cadalene, we designed and synthesized glycosylated cadalene derivatives for improved solubility and efficient drug delivery as a potential prodrug. In vitro cell viability assays confirmed that glycosylated cadalenes were less toxic and more soluble than cadalene. In an in vivo xenograft study in mice, the oral administration of glycosylated cadalenes caused a significant reduction in tumor size.

Glucuronide and sulfate conjugates of ICI 182,780, a pure anti- estrogenic steroid. Order of addition, catalysis and substitution effects in glucuronidation

The 3-sulfate 4 and 3- and 17-glucuronide conjugates 5 and 6 of the pure anti-estrogenic steroid ICI 182,780 1, which is expected to be an effective agent for the treatment of breast cancer, have been prepared. The synthesis of 6 could only be satisfactorily achieved using an inverse addition technique, not previously employed in the glucuronic acid series: the value of this technique for some other aglycones is discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 92420-89-8, you can also check out more blogs about92420-89-8

Olefin coordination in copper(I) complexes of bis(2-pyridyl)amine

Complexes of the type [Cu(H-dpa)(olefin)]BF4 for ethylene (1), propylene (2), 1-butene (3), 1-hexene (4), 1-octene (5), cis-2-octene (6), trans-2-octene (7), cis-3-octene (8), trans-3-octene (9), 2-norbornylene (10), 1,5-cyclooctadiene (11), styrene (12), cis-stilbene (13), trans-stilbene (14), and Ph2CCH2 (15) have been prepared and characterized by 1H and 13C NMR, FTIR, and TGA. The crystal structures have been determined for compounds 5, 6, 8, and 10-13. With the exception of compound 11, copper atoms in each complex are coordinated to the two pyridine nitrogen atoms and the appropriate olefin; consistent with a pseudo three-coordinate Cu(I) cation. Compound 11 has a second weaker pi-interaction resulting in a distorted tetrahedral geometry. Steric hindrance between the olefin and H-dpa manifests as both a twisting of the olefin out of the plane of the H-dpa ligand and a concomitant folding of the H-dpa ligand. The shifts in the nuN-H IR spectral band for H-dpa ligand are consistent with the formation of N-H…F hydrogen bonded interactions observed in the crystal structures. The 1H and 13C NMR spectra of [Cu(H-dpa)(olefin)]BF4 exhibit an upfield shift in the olefin signal as compared to free olefin. A comparison of the Deltadelta values for terminal olefins shows that the similarity of binding for H2CCHR (R = CnH2n+1, n = 1-6) mitigates any preferential complexation of various terminal olefins using the H-dpa ligand. For octenes there is a significant difference in binding between a terminal and internal olefin, but there is little preference between binding for different internal olefins and only a modest difference between the cis and trans isomers of the same olefin. A good correlation exists between the 1H NMR Deltadelta values and the TGA data, confirming that the shift of the olefin NMR resonances upon coordination is associated with the binding strength of the complex. Ab initio calculations using four different method/basis set combinations on the structure of [Cu(H-dpa)(1-octene)]+ were compared with the crystal structure.

Copper(II)nitrito complexes with 2,2′-dipyridylamine. Crystal structures of the [(acetato)(2,2′-dipyridylamine)-(nitrito-O,O’)copper(II)] and [(2,2′-dipyridylamine) (nitrito-O,O’)(mu-nitrito-O)copper(II)]2·2(acetonitrile)

The preparation and characterization of some copper(II)nitrito complexes with 2,2′-dipyridylamine (dipyam) are reported. The X-ray diffraction crystal structures of the [Cu(CH3COO)(dipyam)(ONO-O,O’)] (I) and [Cu(dipyam)(ONO-O,O’)(mu-ONO-O)]2·2CH3CN (II) complexes have been investigated. I consists of two crystallographically independent [Cu(acetato)(dipyam)-(ONO)] neutral complexes, self-assembled by cooperative N-H···O and C-H···O intermolecular interactions in supramolecular tetrameric units. Each copper atom exhibits a tetrahedrally-distorted square-basal geometry of the N2O2 donor set, with the second oxygen atoms of the cis-monodentate nitrito and of the acetato group weakly bound in nearly axial positions. II is a rare example of a dinuclear nitrito copper(II) derivative containing both cis-monodentate and O-bridging nitrito ligands. Each metal ion shows a distorted square-pyramidal coordination with the basal oxygen from the nitrito bridge occupying the axial site of the centrosymmetric complex. The H-bonding between the dipyam amino groups and acetonitrile molecules prevents the self-assembling of the dinuclear complexes. (C) 2000 Elsevier Science B.V.

Discovery and optimization of a novel spiropyrrolidine inhibitor of beta-secretase (BACE1) through fragment-based drug design

The aspartyl protease beta-secretase, or BACE, has been demonstrated to be a key factor in the proteolytic formation of Abeta-peptide, a major component of plaques in the brains of Alzheimers disease (AD) patients, and inhibition of this enzyme has emerged as a major strategy for pharmacologic intervention in AD. An X-ray-based fragment screen of Pfizers proprietary fragment collection has resulted in the identification of a novel BACE binder featuring spiropyrrolidine framework. Although exhibiting only weak inhibitory activity against the BACE enzyme, the small compound was verified by biophysical and NMR-based methods as a bona fide BACE inhibitor. Subsequent optimization of the lead compound, relying heavily on structure-based drug design and computational prediction of physiochemical properties, resulted in a nearly 1000-fold improvement in potency while maintaining ligand efficiency and properties predictive of good permeability and low P-gp liability.
