The present disclosure provides LNPs comprising payload molecules, e.g., mRNA therapeutics, for the treatment of diseases or disorders, which would benefit from delivery of payload molecules to airway cells.

A novel delivery system for drugs, and especially macromolecules such as proteins or oligonucleotides through biological membranes is provided, and specifically delivery of siRNA. The delivery system comprises conjugation of the macromolecule drug to a moiety that enables effective passage through the membranes. Respectively, novel compounds and pharmaceutical compositions are provided, utilizing said delivery system. In one aspect of the invention, the compounds may be utilized in medical practice, for example, in delivery of siRNA or antisense oligonucleotides across biological membranes for the treatment of medical disorders.

The present invention relates to SHIP inhibitor compounds and methods for using these compounds. In particular, the present invention discloses the following methods: (i) a method of treating graft versus host disease in a subject; (ii) a method of inhibiting a SHIP1 protein in a cell; (iii) a method of selectively inhibiting a SHIP1 protein in a cell; (iv) a method for treating or preventing graft-versus-host disease (GVHD) in a recipient of an organ or tissue transplant; (v) a method of modulating SHIP activity in a cell expressing SHIP1 or SHIP2; (vi) a method of ex vivo or in vitro treatment of transplants; (vii) a method of inhibiting tumor growth and metastasis in a subject; (viii) a method of treating a hematologic malignancy in a subject; (ix) a method of inducing apoptosis of multiple myeloma cells; (x) a method of treating multiple myeloma in a subject; (xi) a method of inhibiting the proliferation of a human breast cancer cell; and (xii) a method of treating breast cancer in a subject.

Disclosed in the present invention are a steroid compound, and a preparation method therefor and an application thereof. The steroid compound may have a structure as shown in formula XXI, etc. The compound of the present invention has SREBP pathway inhibitory activity, and can be used for preventing and/or treating diseases such as obesity, hyperlipidemia, fatty liver, diabetes, atherosclerosis, cardiovascular and cerebrovascular diseases, liver cancer, and skin damage.

##STR00001##

The present application provides bifunctional compounds of Formula (Ia):

##STR00001## Targeting Ligand
or an enantiomer, diastereomer, stereoisomer, or pharmaceutically acceptable salt thereof, which act as protein degradation inducing moieties for one or more of cyclin-dependent kinase 8 (CDK8) and cyclin-dependent kinase 19 (CDK19). The present application also relates to methods for the targeted degradation of CDK8 and/or CDK19 through the use of the bifunctional compounds that link a ubiquitin ligase-binding moiety to a ligand that is capable of binding to CDK8 and/or CDK19 which can be utilized in the treatment of disorders modulated by CDK8 and/or CDK19.
