The invention provides anti-VISTA antibody drug conjugates which may be used for targeted delivery of anti-inflammatory agents such as steroids to immune cells, e.g., myeloid cells. The invention also provides methods of using anti-VISTA antibody drug conjugates in the treatment of inflammatory and/or autoimmune conditions and/or for alleviating the toxicity of anti-inflammatory agents such as steroids.

The present invention provides a compound of formula (I) or a salt thereof, wherein R7, R8, R9, G, and X are as defined herein. A compound of formula (I) and its salts have a PKC inhibitory activity, and may be used to treat proliferative disorders.

Novel compounds and methods of using those compounds for the treatment of inflammatory conditions are provided. In a preferred embodiment, modulation of the activation state of p38 kinase protein comprises the step of contacting the kinase protein with the novel compounds.

In the course of the development of N-phenyl-N′-(2-chloroethyl)ureas (CEUs) as potential antineoplastic agents, we investigated the effect of carbonylated substituting chains of the aromatic ring of CEU on their covalent binding to the colchicine-binding site (C-BS). In this study, we found that CEU, 5e, 5f, 8e, and 8f substituted by either a methyl ester or a methyl ketyl group at the ω-position exhibited a significant antiproliferative activity on HT-29, M21, and MCF-7 tumor cells. SDS-PAGE assays and cell cycle analysis confirmed that 5e, 5f, 8e, and 8f covalently bind to the C-BS and arrest the cell division in G2/M phase. Surprisingly, the presence of ω-carboxyl, ω-ethyl esters or ω-amides decreased significantly both the antiproliferative activity and the specificity toward β-tubulin.

New methods for the rational identification of molecules capable of interacting with specific naturally occurring proteins are provided, in order to yield new pharmacologically important compounds and treatment modalities. Broadly, the method comprises the steps of identifying a switch control ligand forming a part of a particular protein of interest, and also identifying a complemental switch control pocket forming a part of the protein and which interacts with said switch control ligand. The ligand interacts in vivo with the pocket to regulate the conformation and biological activity of the protein such that the protein assumes a first conformation and a first biological activity upon the ligand-pocket interaction, and assumes a second, different conformation and biological activity in the absence of the ligand-pocket interaction. Next, respective samples of said protein in the first and second conformations are provided, and these are screened against one or more candidate molecules by contacting the molecules and the samples. Thereupon, small molecules which bind with the protein at the region of the pocket may be identified. Novel protein-modulator adducts and methods of altering protein activity are also provided.

Novel compounds and methods of using those compounds for the treatment of inflammatory conditions, hyperproliferative diseases, cancer, and diseases characterized by hypervascularization are provided. In a preferred embodiment, modulation of the activation state of p38 kinase protein ab1 kinase protein, bcr-ab1 kinase protein, braf kinase protein, VEGFR kinase protein, or PDGFR kinase protein comprises the step of contacting said kinase protein with the novel compounds.

This invention relates to novel compounds of Formula (I) for use as vascular damaging agents: Formula (I) wherein Rl, R7, R8, R9, ARI, AR2, AR3, p, q and r are as described in the specification. The invention also relates to methods for preparing compounds of Formula (I), to their use as medicaments (including methods for the treatment of angiogenesis or disease states associated with angiogenesis) and to pharmaceutical compositions containing compounds of Formula (I).

One-carbon homologation of aldehyde into amide is realized in one-pot by its reaction with potassium α-p-methoxyphenyl-α-isocyano acetic acid (1c) and hydrochloride salt of dimethylamine (3a) in toluene at room temperature followed by acidic workup. In this multicomponent reaction, 1c served as donor of the CONH2 function to aldehyde, while the dimethylamine acted as a shuttle molecule to initiate/terminate the sequence and to mediate the internal redox process of one of the three-component adducts. Ready accessibility, nominal cost of the reagents, and mild conditions are attractive features of the present method. Copyright
