This invention is an azo pigment composition containing a water insoluble metal salt of a water soluble polymer; a method of preparing said composition and ink compositions prepared from said azo pigment compositions.
we developed the divergent organocatalytic cascade approach to efficiently construct a focused library with scaffold diversity and successfully identified a novel spiropyrazolone antitumor scaffold. Herein, a series of spiropyrazolone derivatives were designed, synthesized and assayed. Most of them showed good in vitro antitumoractivity with a broad spectrum. Preliminary structure–activity relationship
Invented are non-peptide TPO mimetics. Also invented is a method of treating thrombocytopenia, in a mammal, including a human, in need thereof which comprises administering to such mammal an effective amount of a selected hydroxy-1-azobenzene derivative.
