Abstract:
The present invention involves an improved process for the preparation of Indocyanine green of Formula (I) having high purity of about 99%, wherein the process comprises steps of reacting 1,1,2-trimethyl-1H-benzo[e]indole with 1,4-butane sulfone in boiling solvent to give 4-(1,1,2-trimethyl-1H-benzo[e]indolium-3-yl)butane-1-sulfonate. Followed by reacting 4-(1,1,2-trimethyl-1H-benzo[e]indolium-3-yl)butane-1-sulfonate of Formula (IV) and N-phenyl-N-((1E,3E,5E)-5-(phenylimino)penta-1,3-dienyl)acetamide of formula (V) in presence of sodium acetate and alcohol; and extracting the title compound formula (I) with an ester solvent.
Abstract:
There are described RORϒ modulators of the formula (I), and formula (II) or stereoisomers, tautomers, pharmaceutically acceptable salts, solvates, or prodrugs thereof, wherein all substituents are defined herein. Also provided are pharmaceutical compositions comprising the same. Such compounds and compositions are useful in methods for modulating RORϒ activity in a cell and methods for treating a subject suffering from a disease or disorder in which the subject would therapeutically benefit from modulation of RORϒ activity, for example, autoimmune and/or inflammatory disorders.
Abstract:
The invention relates to nucleophile-reactive sulfonated compounds used as precursors to (radio)labelled (bio)molecules suitable mainly for medical applications. The aim of the invention is to provide novel prosthetic compounds or groups, the synthesis of which is straightforward, easy and automatable, enabling access to economical and effective, (radio)labelled, complex and fragile - especially water-soluble and more especially amine-containing- (bio)molecules. The aim is achieved by the invention, which involves precursors and compounds of respective formulae (Ip), (I). Said nucleophile-reactive sulfonated compounds are produced by pre-introduction of a nucleophilic compound R*, e.g. Fluorine- 18, through an unusal nucleophile-induced ring-opening reaction of the sultone (e.g. 1,3-propanesultone) moiety of the precursor. The invention also relates to the methods for producing the abovementioned precursors and compounds, as well as for the conjugation of these compounds with (bio)molecules, and to the drugs obtained through this method.

Abstract:
This invention relates to analogs of the DNA -alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and conjugates. The conjugates are designed to release their (multiple) payload after one or more activation steps and/or at a rate and time span controlled by the conjugate in order to selectively deliver and/or controllably release one or more of said DNA alkylating agents. The agents, conjugates, and intermediates can be used to treat an illness that is characterized by undesired (cell) proliferation. As an example, the agents and the conjugates of this invention may be used to treat a tumor.

Abstract:
The present invention relates to novel compounds, more precisely to novel bifunctional prodrugs and drugs. In a further aspect, the invention relates to pharmaceutical compositions comprising said prodrugs and drugs, and to the use thereof as cytostatic agents in tumor therapy. The compounds according to the invention thereby are based on CC- 1065 analogously.
Abstract:
The present invention relates to compounds derived from taurine with non-steroidal anti inflammatory activity. In a first embodiment, the present invention relates to compounds derived from taurine, in which taurine is bound directly by means of an amide bond or through an spacing group, to a compound selected from the group of non-steroidal anti inflammatory compounds, cited as derived from taurine presenting the Formula (I): in which R means the component with non-steroidal anti inflammatory activity. In a second embodiment, the invention provides a process for obtaining the compounds of Formula (I) by reaction of taurine with a compound belonging to the group of non-steroidal anti inflammatory (NSAIs), in order to obtain a compound derived from taurine by direct bond or through a spacing group of the taurine to the NSAI. The invention also relates to the pharmaceutical compositions comprising at least one compound derived from taurine presenting non-steroidal anti inflammatory activity.
