The anti-cancer agent of the present invention contains at least one kind of phosphine transition metal complex selected from a group of compounds represented by the following Formulae (1a) to (1d). According to this anti-cancer agent, an anti-cancer agent is provided which has a higher anti-cancer activity and lower toxicity compared to anti-cancer agents in the related art. In Formulae (1a), (1b), (1c), and (1d), R.sup.1 and R.sup.2 represent a linear or branched alkyl group, and R.sup.1 has a higher priority than R.sup.2 as ranked according to RS notation. R.sup.3 and R.sup.4 represent a hydrogen atom or a linear or branched alkyl group. M represents an atom of a transition metal selected from a group consisting of gold, copper, and silver. X.sup. represents an anion. ##STR00001##

The present invention provides crystalline forms of the chloride monohydrochloride salt of fosnetupitant, methods of making the crystalline forms, and pharmaceutical dosage forms that make use of the crystalline forms.

Provided are a sulfur/phosphorus-containing aryl compound and an application thereof, and specifically disclosed are a compound represented by formula (V) and a pharmaceutically acceptable salt thereof.

The present invention relates to a novel [4-(1,3,3-trimethyl-2-oxo-3,4-dihydro-1H-quinoxalin-7-yl)phenoxy]ethyloxy compound or a salt thereof. The compound or a salt thereof of the present invention has a glucocorticoid receptor agonist activity, and is useful as a medicine, in particular as a prophylactic or therapeutic agent for the glucocorticoid receptor related disease.

The present disclosure provides compounds that are useful for inhibiting the STAT6 pathway. Also provided are related pharmaceutical compositions and methods of using the compounds. In some embodiments, the compounds may be used to treat a disease such as, e.g., an allergic lung disease, allergic rhinitis, chronic pulmonary obstructive disease, or a cancer.

The present disclosure provides phosphonate-containing heterocycle compounds with TYK2 kinase inhibitory activity, pharmaceutical compositions comprising the same, and applications thereof. The present disclosure provides compounds of Formula (I), as inhibitors of TYK2 kinase. These compounds can be used for preventing and/or treating TYK2 kinase-related diseases and/or conditions.

##STR00001##

Disclosed are compounds, compositions and methods for the prevention and/or treatment of diseases which are pathophysiologically mediated by the neurokinin (NK.sub.1) receptor. The compounds have the general formula (I):

##STR00001##

The present invention relates to novel compounds and probes which have a common chemical structure necessary to obtain potent inhibitory activity against KLK4 and/or may be used for the detection of KLK4 peptides and their activity. It further relates to the use of these compounds and methods for inhibiting and/or detecting KLK4 activity in vitro and in vivo by making use of said probes or inhibitors. The compounds of the invention differ from prior art compounds at least in the presence of phenyl guanidine (instead of e.g. benzyl guanidine) and/or the presence of a heteroatom in the tail group, their combined presence unexpectedly leading to potent and selective KLK4 inhibitory activity.

The invention provides a method for the synthesis of dehydrogenated lactam drugs of Formula I: ##STR00001##

The present invention provides crystalline forms of the chloride monohydrochloride salt of fosnetupitant, methods of making the crystalline forms, and pharmaceutical dosage forms that make use of the crystalline forms.
