these molecules are assembled through the stepwise introduction of a reactivity handle in place of an aromatic C-H bond (that is, a nitro group, halogen or boronic acid) and a subsequent functionalization or cross-coupling. Here we show that aromaticamines can be constructed by direct reaction of arenes and alkyl amines using photocatalysis, without the need for pre-functionalization. The process
straightforward approach involves in situ formation and photoinduced activation of N‐chloroamines to give aminium radicals that enable efficient alkene aminochlorination. Owing to the ambiphilic nature of the β‐chloroamines produced, conversion into tetra‐alkyl aziridinium ions was possible, thus enabling diamination by regioselectivering‐opening with primary or secondary amines. This strategy streamlines
Compounds are provided that act as potent antagonists of the CCR1 receptor, and have in vivo anti-inflammatory activity. The compounds are generally monocyclic and bicyclic compounds and are useful in pharmaceutical compositions, methods for the treatment of CCR1-mediated diseases, and as controls in assays for the identification of competitive CCR1 antagonists.
A compound of formula (I) for use in the treatment or prevention of mental diseases
A is N, CH, C having a double bond or CR5; each of B and Z is independently N, CH or CR1, with the proviso that A is N when B and/or Z is N; R1, R2, R3, R4 and R5 and n are as defined in the specification.

The present invention provides methods for treating sepsis, systemic inflammatory response syndrome, severe sepsis, septic shock, and multiple organ dysfunction syndrome by modulating NF-κB transcription with ligands that interact with the estrogen receptor, preferably in the absence of classic estrogenic activity. Other aspects of the invention relate to methods for treating sepsis, systemic inflammatory response syndrome, severe sepsis, septic shock, and multiple organ dysfunction syndrome that comprise administering to a patient suffering therefrom an effective amount of a compound of Formula I:
