New synthetic route to granulatimide and its structural analogues.

The Stille coupling reaction of stannylindole 12 with 4-iodoimidazole 13 (or 24) in the presence of PdCl(2)(PPh(3))(2) gave the corresponding indole-imidazole coupling product 14 (or 25), thereby affording a new synthetic approach to the alkaloid granulatimide (7), isolated from the Brazilian ascidian Didemnum granulatum, as well as its structural analogues, 10-methylgranulatimide (23), 17-methylgranulatimide (30), 10,17-dimethylgranulatimide (31).

Systems pharmacology-based dissection of the active ingredients and targets of Yiqi Zishen formula for application to COPD

In this work, a systems pharmacology model based on the pharmacokinetic analysis, drug targeting, and drug-target-disease network analyses, was applied specifically to uncover the active ingredients and therapeutic targets of Yiqi Zishen formula (YZF). Furthermore, a rat model of cigarette smoke-and bacterial infection-induced chronic obstructive pulmonary disease (COPD) was applied to evaluate the effects of YZF on COPD and its comorbidity. The expression of interleukin (IL)-1beta, IL-6, tumor necrosis factor (TNF)-alpha, soluble TNF-alpha receptor (sTNFR2), matrix metalloproteinase (MMP)-2, MMP-9, tissue inhibitor of MMP (TIMP)-1, endothelin (ET)-1, transforming growth factor (TGF)-beta, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) were analyzed by immunohistochemistry. The pharmacological system efficiently generated 158 active compounds from YZF, and predicted 192 potential targets. The result showed that there was a significant target overlap between the 12 herbs in the YZF formula, which means that each herb of YZF connected with the similar targets, implying the synergistic effects among them. The target-disease network results indicated that YZF was effective in treating various pathological conditions, including respiratory tract diseases, cardiovascular disease, immune system diseases, and nervous system diseases. The therapeutic mechanisms of YZF were probably associated with modulation of inflammatory response, immune responses, matrix metalloproteinases expression, among others. In follow-up experiments, we found that YZF was effective for the treatment of COPD and its comorbidity such as ventricular hypertrophy, by inhibiting the expression of inflammatory cytokine, matrix metalloproteinases, and hypertrophic stimuli and collagen, in vivo.

Synthesis and in vitro testing of new potent polyacridine-melittin gene delivery peptides

The combination of a polyacridine peptide modified with a melittin fusogenic peptide results in a potent gene transfer agent. Polyacridine peptides of the general formula (Acr-X)n-Cys were prepared by solid-phase peptide synthesis, where Acr is Lys modified on its epsilon-amine with acridine, X is Arg, Leu, or Lys and n is 2, 3, or 4 repeats. The Cys residue was modified by either a maleimide-melittin or a thiolpyridine-Cys-melittin fusogenic peptide resulting in reducible or non-reducible polyacridine-melittin peptides. Hemolysis assays established that polyacridine-melittin peptides retained their membrane lytic potency relative to melittin at pH 7.4 and 5. When combined with plasmid DNA, the membrane lytic potency of polyacridine-melittin peptides was neutralized. Gene transfer experiments in multiple cell lines established that polyacridine-melittin peptides mediate expression as efficiently as PEI. The expression was very dependent upon a disulfide bond linking polyacridine to melittin. The gene transfer was most efficient when X is Arg and n is 3 or 4 repeats. These studies establish polyacridine peptides as a novel DNA binding anchor peptide.

HYDROXYALKYLAMINOALKYLTHIOXANTHONES

Novel, UV radiation hydroxyalkylaminoalkylthioxanthone photoinitiators are disclosed having a hydroxyalkylaminoalkyl group, which can be in the third conjugated ring at the ortho or meta positions thereof. The hydroxyalkylaminoalkyl group comprises a tertiary amine and at least one hydroxy group in proximity to one another such that the hydroxyalkylaminoalkylthioxanthone can increase the rate of polymerization of a photo-curable compound and the polymerized product can be formed into a cured film substantially free of extractable residues.

Multicomponent reaction-based synthesis and biological evaluation of tricyclic heterofused quinolines with multi-trypanosomatid activity

Human African trypanosomiasis (HAT), Chagas disease and leishmaniasis, which are caused by the trypanosomatids Trypanosoma brucei, Trypanosoma cruzi and Leishmania species, are among the most deadly neglected tropical diseases. The development of drugs that are active against several trypanosomatids is appealing from a clinical and economic viewpoint, and seems feasible, as these parasites share metabolic pathways and hence might be treatable by common drugs. From benzonapthyridine 1, an inhibitor of acetylcholinesterase (AChE) for which we have found a remarkable trypanocidal activity, we have designed and synthesized novel benzo[h][1,6]naphthyridines, pyrrolo[3,2-c]quinolines, azepino [3,2-c]quinolines, and pyrano[3,2-c]quinolines through 2e4-step sequences featuring an initial multicomponent Povarov reaction as the key step. To assess the therapeutic potential of the novel compounds, we have evaluated their in vitro activity against T. brucei, T. cruzi, and Leishmania infantum, as well as their brain permeability, which is of specific interest for the treatment of late-stage HAT. To assess their potential toxicity, we have determined their cytotoxicity against rat myoblast L6 cells and their AChE inhibitory activity. Several tricyclic heterofused quinoline derivatives were found to display an interesting multi-trypanosomatid profile, with one-digit micromolar potencies against two of these parasites and two-digit micromolar potency against the other. Pyranoquinoline 39, which displays IC50 values of 1.5 muM, 6.1 muM and 29.2 muM against T. brucei, L. infantum and T. cruzi, respectively, brain permeability, better drug-like properties (lower lipophilicity and molecular weight and higher CNS MPO desirability score) than hit 1, and the lowest AChE inhibitory activity of the series (IC50 30 mM), emerges as an interesting multi-trypanosomatid lead, amenable to further optimization particularly in terms of its selectivity index over mammalian cells.

Chemoenzymatic synthesis of prodigiosin analogues – Exploring the substrate specificity of PigC

ATCC 39006 or to engineered strains of Escherichia coli; in this way it has been shown that the prodigiosin synthesising enzyme, PigC, has a relaxed substrate-specificity.
