Disclosed are compounds, compositions and methods for the prevention and/or treatment of diseases which are pathophysiologically mediated by the neurokinin (NK.sub.1) receptor. The compounds have the general formula (I):

##STR00001##

The present disclosure provides reagents that can be used to label synthetic oligonucleotides with rhodamine dyes or dye networks that contain rhodamine dyes.

Disclosed are compounds of Formulas (I), (II), (III), (IV), and (V): ##STR00001##
and/or a salt thereof, wherein R.sub.1 is —OH or —OP(O)(OH).sub.2, and X.sub.1, X.sub.2, X.sub.3, R.sub.2, R.sub.2a, R.sub.a, R.sub.b, and R.sub.c are defined herein. Also disclosed are methods of using such compounds as selective agonists for G protein-coupled receptor S1P.sub.1, and pharmaceutical compositions comprising such compounds. These compounds are useful in treating, preventing, or slowing the progression of diseases or disorders in a variety of therapeutic areas, such as autoimmune diseases and vascular disease.

Compounds represented by Formula (I) and (II) and salts thereof are described herein. The compounds or salts of Formula (I) and (II) may be used to treat senescence-associated diseases and disorders. ##STR00001##

Disclosed herein, inter alia, are compounds for binding STRAD pseudokinase and uses thereof.

Dye and compositions to monitor the multistep protein aggregation process in both test tubes and live cells are provided. These dyes can detect misfolded protein oligomers and distinguish insoluble protein aggregates from misfolded oligomers. Applications of these dyes include measuring kinetics of protein aggregation, monitoring aggregation of specific proteins in intact live cells, monitoring aggregation of cellular proteome in intact live cells, and tracking the time course of protein aggregation in cells under stress conditions.

The aryl sulfonamide compounds of this invention have powerful and cell-type specific Bcl inhibitory activity. Selected compounds in this class promote apoptosis in senescent cells, and are being developed for treating senescent-related conditions. Selected compounds in this class promote apoptosis in cancer cells, and can be developed as chemotherapeutic agents.

The present disclosure relates to biomimetic nanomaterials, compounds, compositions, and methods for delivery of therapeutic, diagnostic, or prophylactic agents (for example, a nucleic acid).

The present invention discloses a compound with the following formula (I), or a tautomer, mesomer, racemate, enantiomer, and diastereoisomer thereof, or a mixture form thereof, or a pharmaceutically acceptable salt thereof, or a prodrug molecule thereof, wherein D is selected from:

##STR00001##

The invention further discloses the use of the compound in the preparation of drugs for preventing and/or treating cancers, and the use of the compound in the preparation of drugs for inhibiting cancer metastasis. The compound of the present invention can effectively inhibit the proliferation and metastasis of cancer cells by adjusting the acidity of a tumor microenvironment to achieve a better effect in clinical cancer treatment, and has broad application prospects.

##STR00002##
