摘要:
Since a compound represented by the general formula (I) (wherein definition of each group is as described in the specification), a salt thereof, a solvate thereof, or a prodrug thereof has strong and sustaining intraocular pressure lowering activity and, further, has no side effect on eyes such as ocular stimulating property (hyperemia, corneal clouding etc.), aqueous humor protein rise etc., it has high safety, and can be an excellent agent for preventing and/or treating glaucoma etc.
摘要:
The present invention provides a compound of the formula (I) wherein R1 is -H, -OH, -O(C1-C4 alkyl), -OCOC6H5, -OCO(C1-C6 alkyl), or -OSO2(C2-C6 alkyl); R0, R2 and R3 are each independently -H, -OH, -O(C1-C4 alkyl), -OCOC6H5, -OCO(C1-C6 alkyl), -OSO2(C2-C6 alkyl) or halo; R4 is 1-piperidinyl, 1-pyrrolidinyl, methyl-1-pyrrolidinyl, dimethyl-1-pyrrolidinyl, 4-morpholino, dimethylamino, diethylamino, diisopropylamino, or 1-hexamethyleneimino; n is 2 or 3 X is -S- or -HC=CH-; G is -O-, -S-, -SO-, SO2, or -N(R5)-, wherein R5 is -H or C1-C4 alkyl; and Y is -O-, -S-, -NH-, -NMe-, or -CH2-; or a pharmaceutically acceptable salt thereof; pharmaceutical compositions thereof, optionally in combination with estrogen and progestin; methods of inhibiting a disease associated with estrogen deprivation; and methods for inhibiting a disease associated with an aberrant physiological response to endogenous estrogen.

This invention is related to heteroatom containing diamondoids (i.e., 'heterodiamondoids' ) which are compounds having a diamondoid nucleus in which one or more of the diamondoid nucleus carbons has been substitutionally replaced with a noncarbon atom. These heteroatom substituents impart desirable properties to the diamondoid. In addition, the heterodiamondoids are functionalized affording compounds carrying one or more functional groups covalently pendant therefrom. This invention is further related to polymerizable functionalized heterodiamondoids. In a preferred aspect of this invention the diamondoid nuclei are triamantane and higher diamondoid nuclei. In another preferred aspect, the heteroatoms are selected to give rise to diamondoid materials which can serve as n- and p-type materials in electronic devices can serve as optically active materials.

Disclosed herein are compounds, compositions, and methods to inactivate a virus and destroy tumor cells. The methods involve the addition into the cell of a compound containing a photosensitizing chemical and an energy donating chemical, optionally linked by a chemical tether. Also introduced into the cell are means to chemically active the energy donating chemical which photoactivates es the photosensitizing chemical which then destroys the tumor or virus. The photosensitizing chemical is preferably hypericin, porphyrin, or an analog and the energy donating chemical is preferably luciferin or an analog. Methods for synthesizing the chemicals are also disclosed. Further, the energy donating chemical is activated by an activating chemical. Expression of the activating chemical is regulated so that it is only expressed in the virus-infected or tumor cells. Regulating the activating chemical is accomplished by a number of methods including construction of an expression plasmid containing a gene encoding the activating chemical under control of a promoter which is transactivated by replication of the virus or transactivated by elevated levels of proteins expressed in tumor cells.
