Patent number: 6028103Abstract: 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.Type: GrantFiled: March 19, 1997Date of Patent: February 22, 2000Assignees: Children's Medical Center Corporation, Ion Pharmaceuticals, Inc.Inventors: Carlo Brugnara, Jose Halperin, Emile M.

Patent number: 5990335Abstract: A di-p-tolyldialkylsilane derivative, a photoluminescence polymer formed from the derivative, and methods for preparing the derivative and polymer are provided. The di-p-tolyldialkylsilane derivative is represented by the following formula (1): ##STR1## where R.sub.1 and R.sub.2 are independently selected from the group consisting of phenyl and --(CH.dbd.CH).sub.k R.sub.3 (k is an integer between and inclusive of 0 and 2, and R.sub.3 is hydrogen or alkyl), and X.sup.2 is selected from the group consisting of hydrogen, halogen atom and cyano group. The di-p-tolylalkylsilane derivative of the formula (1) is very useful as a monomer of a functional polymer. The photoluminescence polymer formed from the di-p-tolylalkylsilane derivative of the chemical formula (1) contains a repeating unit having a silicon between the conjugated double bonds, thereby suppressing electron movement of the conjugated double bond. As a result, a range of colors between blue and green, particularly, blue, can be obtained.Type: GrantFiled: January 8, 1998Date of Patent: November 23, 1999Assignee: Samsung Display Devices Co., Ltd.Inventors: Hwan-kyu Kim, Soo-min Lee, Mi-kyung Ryu, Ki-dong Kim

Patent number: 5968863Abstract: It is possible to prepare in high yield and purity the racemic and meso forms of bridged chiral metallocenes with a stereoselective method, by synthesizing the sylil-, germyl- or stannyl-substituted ligands. These compounds can be prepared in their racemic and meso forms, and then selectively transformed in the corresponding metallocenes.Type: GrantFiled: January 23, 1996Date of Patent: October 19, 1999Assignee: Montell Technology Company B.V.Inventors: Ilya E. Nifant'ev, Pavel V. Ivchenko, Luigi Resconi
