Described herein are silicon based conjugates capable of delivering one or more payload moieties to a target cell or tissue. Contemplated conjugates may include a silicon-heteroatom core, one or more optional catalytic moieties, a targeting moiety that permits accumulation of the conjugate within a target cell or tissue, one or more payload moieties (e.g., a therapeutic agent or imaging agent), and two or more non-interfering moieties covalently bound to the silicon-heteroatom core.
The present invention provides compounds and compositions thereof which are useful as inhibitors of plasma kallikrein and which exhibit desirable characteristics for the same.

efficient and convenientmethod for the synthesis of [1,2,4]triazolo[4,3-a]pyridines was exemplified by the synthesis of 20 analogues bearing a variety of substituents at the 3-position. The methodology involves a palladium-catalyzed addition of hydrazides to 2-chloropyridine, which occurs chemoselectively at the terminal nitrogen atom of the hydrazide, followed by dehydration in acetic acid under microwave
合成[1,2,4]三唑并[4,3- a ]吡啶的一种有效而方便的方法,是通过合成20个在3位带有取代基的类似物来举例说明的。该方法包括将钯催化的酰肼加成至2-氯吡啶,其在酰肼的末端氮原子上发生化学选择性,然后在微波辐射下于乙酸中脱水。

A compound having the following general formula (I):
wherein:
X is a nitrogen atom and Y is a carbon atom; or
X is a carbon atom and Y is a nitrogen atom;
the Ar group is an aryl or heteroaryl group; and
the RN and RN′ groups, together with the carbon atoms to which they are bound, form a monocyclic or bicyclic azacycloalkane group. The pharmaceutically acceptable salts thereof, the hydrates or polymorphic crystalline structures thereof, and to the racemates, diastereoisomers, or enantiomers thereof are also described.
