The present disclosure relates to small molecule inhibitors of proprotein convertase subtilisin-like / kexin type 9 (PCSK9), pharmaceutical compositions comprising said compounds, and their use in the prevention and treatment of diseases and disorders associated with PCSK9.

The invention belongs to the technical field of cosmetics, and provides a preparation method of a piper nigrum root extract and application of the piper nigrum root extract in pain relieving cosmetics. The kava pepper root extract is prepared by the following steps: crushing kava pepper roots, and performing alcohol extraction; carrying out secondary extraction by using a small molecular polyol solution containing isopropyl acetate; combining the extracting solutions, and adding compound enzymes (cellulase, pectinase and subtilisin) for enzymolysis to obtain a crude extract; and finally, carrying out subcritical extraction and purification on the crude extract to obtain the product. Through improvement of extraction and purification processes, the extraction rate of active ingredients is effectively increased, a certain amount of glutathione is obtained, and toxicity is reduced; the invention also discovers that the composition ratio of the active ingredients of the extract obtained by the optimized process is in a proper range, and the anti-inflammatory and analgesic effects of the Kava pepper root extract are further improved.

Disclosed are, inter alia, double stranded RNAi (dsRNAi) agents inhibiting expression of proprotein convertase subtilisin kexin 9 (PCSK9), for example, human PCSK9, compositions including the same, and methods of treatment using the same.

The variant has at least about 80% identity to the amino acid sequence of SEQ ID NO: 1.

An siRNA which inhibits proprotein convertase subtilisin / kexin type 9 (PCSK9) gene expression, a pharmaceutical composition containing the siRNA, and a conjugate. Each nucleotide in the siRNA is independently a modified or unmodified nucleotide. The siRNA contains a sense strand and an antisense strand. The sense strand contains nucleotide sequence I; nucleotide sequence I having the same length as the nucleotide sequence shown in SEQ ID NO: 1, with no more than three nucleotides differences. The antisense strand contains nucleotide sequence II, nucleotide sequence II having the same length as the nucleotide sequence shown in SEQ ID NO: 2, with no more than three nucleotides differences. The siRNA, pharmaceutical composition thereof and the conjugate can effectively treat and / or prevent hypercholesterolemia.

Disclosed are, inter alia, combinations comprising a first antisense (e.g., first double stranded RNAi (dsRNAi)) agent for inhibiting expression of proprotein convertase subtilisin kexin 9 (PCSK9), for example, human PCSK9, and a second antisense agent (e.g., second dsRNAi agent) for inhibiting expression of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR); pharmaceutical compositions including the same, and methods of treatment using the same.

Disclosed herein is one or more subtilisin variant, nucleic acid encoding same, and compositions and methods related to the production and use thereof, including one or more subtilisin variant that has improved stability and / or soil removal compared to one or more reference subtilisin.

Disclosed are, inter alia, double stranded RNAi (dsRNAi) agents inhibiting expression of proprotein convertase subtilisin kexin 9 (PCSK9), for example, human PCSK9, compositions including the same, and methods of treatment using the same.

The invention provides a pharmaceutical composition for resisting inflammation and repairing oral ulcer and a preparation method thereof, and belongs to the technical field of biological pharmacy, and the pharmaceutical composition comprises ciona glabra peptide, a cucurbita pepo seed extract, carboxymethylation modified hemerocallis citrina root polysaccharide, honeysuckle chlorogenic acid, baicalin and dipotassium glycyrrhizinate. The ciona ciona peptide is prepared by carrying out step-by-step enzymolysis on ciona ciona through trypsin and lumbrukinase and purifying through a sephadex G-15 column. The cucurbita pepo seed extract is prepared by breaking walls of cucurbita pepo seeds with a compound enzyme, performing enzymolysis with ficin protease and subtilisin, and purifying with a polyamide resin column. The carboxymethylation modified hemerocallis citrina root polysaccharide is prepared by alkalization and chloroacetic acid modification of hemerocallis citrina root extracted polysaccharide. All the components are compounded for use, so that multiple effects of resisting inflammation, easing pain and promoting epithelial cell proliferation and mucosal barrier repair are synergistically realized, and the treatment effect of oral ulcer is optimized.

The present invention provides variant subtilisins and compositions comprising at least one variant subtilisin set forth herein, as well as methods for using these variants and compositions. In some embodiments, the present invention provides variant subtilisins suitable for laundry cleaning applications.

This invention discloses a formulation for pet oral cleaning and softening of dental plaque and tartar, and its preparation method, belonging to the technical field of pet oral cleaning formulations. The formulation comprises the following components: 0.5%-2.0% complex protease, 0.3%-1.2% repair agent, 0.05%-0.2% antibacterial agent, 0.2%-0.8% probiotic active liquid, 0.03%-0.3% metal chelating agent, 0.1%-2% emulsifier, 5%-15% humectant, 0.01%-0.3% breath freshener, 0.1%-0.5% pH adjuster, and the balance purified water. The complex protease is composed of subtilisin, bromelain, and papain. This invention, through the combination of a multi-enzyme synergistic system and active components, achieves effective removal of pet dental plaque and a significant softening and peeling effect on dental tartar. The resulting formulation is compatible with the pet's oral physiological environment, and long-term use can effectively prevent the occurrence of oral diseases.
