Identification and Use of Non-Peptide Analogs of RNAIII-Inhibiting Peptide for the Treatment of Staphylococcal Infections

InactiveUS20070293435A1Reduce and prevent sameAvoid bacterial infectionBiocideOrganic active ingredientsPharmacophoreHamamelitannin
RNAIII inhibiting peptide (RIP) has been established as an effective inhibitor of staphylococcal infections. Non-peptide small molecule analogs based on a pharmacophore conforming to the putative atomic structure of RIP, can be identified by computer screening of that pharmacophore against established libraries of known small molecules other than peptides. One such identified structural analog is hamamelitannin. When tested for effective inhibition of staphylococcal infections, hamamelitannin demonstrated inhibition similar to that exhibited by RIP. Other analogs can be identified and similarly used.

Cryptic metabolites and method for activating silent biosynthetic gene clusters in diverse microorganisms

Microorganisms are prolific producers of natural products and are a group of molecules that make up the majority of drugs approved by the FDA in the past 35 years. After decades of mining, the low-hanging fruit has been picked and so the discovery of drug-like molecules from microorganisms has come to a near-halt. The reason for this lack of productivity is that most biosynthetic pathways that give rise to natural products are not active under typical laboratory growth conditions. These so-called cryptic or silent pathways are a major source of new bioactive molecules and methods that reliablyactivate them could have a profound impact on drug discovery. Disclosed herein is a rapid genetics-free method for eliciting and detecting cryptic metabolites using an imaging mass spectrometry-basedapproach. An organism of choice is challenged with elicitors from a small molecule library. The molecules elicited are then imaged by mass spec, which allows for rapid identification of cryptic metabolites. The cryptic metabolites are then isolated and characterized. The use of disclosed methods activates the production of recessive glycopeptides from actinomycete bacteria. The resulted molecules, the keratinimicins and keratinicyclins, are metabolites with important structural features. At least two of these, namely keratinimicins B and C, are highly bioactive against several pathogenic strains. The approach will allow for the rapid activation and identification of cryptic metabolites from diverse microorganisms in the future.

Anti-inflammatory inhibitor screening model taking MyD88TIR (myeloid differentiation primary response protein 88 Toll/interleukin-1 receptor) dimerization as target point and application thereof

The invention relates to an anti-inflammatory inhibitor screening model taking MyD88TIR (myeloid differentiation primary response protein 88 Toll / interleukin-1 receptor) dimerization as a target point and application thereof. The anti-inflammatory inhibitor screening model taking the MyD88TIR dimerization as the target point is characterized in that: an MyD88TIR builds fusion protein plasmids together with protein genes GFP / RFP (Green fluorescent protein / Red fluorescent protein) of a fluorescence donor and a fluorescent receptor, and the fusion protein plasmids are transfected into mammalian cells to build dual-positive expression cell strains; the FRET (fluorescence resonance energy transfer) phenomenon can be detected; when an MyD88TIR dimerization inhibitor exists in a culture medium, the cell strains which depend on dual-positive to express GFP-MyD88-TIR and RFP-MyD88-TIR are suggested, and whether the inhibitor directly blocks the interaction of the TIRs or not can be further determined according to in vitro binding analysis; and combined with the fluorescent FRET blocking results of eukaryotic cells and prokaryotic expression recombinant protein interaction analysis, the MyD88TIR dimerization inhibitor can be determined. The model can be used for widely screening commercialized small molecule libraries, self-prepared natural product components, or various chemical compounds, and modifiers, from which MyD88 dimerization inhibitory compounds are obtained to participate in the drug screening of MyD88 signal pathway-dependent chronic inflammation and autoimmune diseases.

In-vitro efficient preparation method and application of mesenchymal stem cells derived from human inducible pluripotent stem cells

The invention discloses an in-vitro efficient preparation method and application of mesenchymal stem cells derived from human inducible pluripotent stem cells. The preparation method comprises the following steps: 1) culturing and amplifying human inducible pluripotent stem cells (hiPSCs); 2) through the strategy of library screening and combination optimization of chemical small molecules, jointly treating the hiPSCs for nine days by utilizing two chemical small molecules, namely LLY-507 and AZD5153 so as to obtain hiPSC-derived mesenchymal precursor cells with a CD73 positive mesenchymal stem cell proportion of 80% or above; 3) subculturing the mesenchymal precursor cells twice to obtain further mature CD73<+>CD105<+> hiPSC-derived mesenchymal stem cells (hiPSC-MSCs); and 4) identifyingthe prepared CD73<+>CD105<+> hiPSC-derived cells as mesenchymal stem cells on the basis of immunological means and cytobiological analysis. Experimental results prove that through usage of the chemical small molecule combination treatment strategy, the efficiency of producing the mesenchymal stem cells by differentiation of the hiPSCs can be substantially improved; and low-expression pluripotencyrelated marker molecules of the hiPSC-MSCs have the typical functions of adipogenesis, osteogenesis and chondrogenesis differentiation and low immunogenicity, and can be used for treating immune related diseases.
