Abstract: Disclosed are blue, diol anthraquinone blue colorant compounds having excellent thermal stability and which can be reacted into or copolymerized with polyester thus providing a blue-colored polyesters useful for manufacturing a variety of shaped articles such as photographic film base, particularly roentgenographic (X-ray) film. Also disclosed are blue anthraquinone colorant compounds which contain two ethylenically-unsaturated (vinyl), photopolymerizable radicals which may be derived from the aforesaid diol anthraquinone compounds. The anthraquinone colorant compounds containing two ethylenically-unsaturated may be reacted into or copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored vinyl polymers.

Abstract: The present invention provides a class of chemical compounds useful as efficacious drugs in the treatment of sickle cell disease and diseases characterized by unwanted or abnormal cell proliferation. The active compounds are substituted triaryl methane compounds or analogues thereof where one or more of the aryl groups is replaced with a heteroaryl, cycloalkyl or heterocycloalkyl group and/or the tertiary carbon atom is replaced with a different atom such as Si, Ge, N or P. The compounds inhibit mammalian cell proliferation, inhibit the Gardos channel of erythrocytes, reduce sickle erythrocyte dehydration and/or delay the occurrence of erythrocyte sickling or deformation.
