چکیده
The structure of an S2O mixed-donor macrocycle incorporating para-substituted xylyl subunit was characterized by a single crystal X-ray analysis. The crystal structure shows an exo-dentate orientation of sulfur and oxygen donor atoms due to the fully stretched aliphatic ring conformation. Thus all of torsional angles between donor atoms are arranged anti and S...S distance in a ring is 6.764(1)A, which is larger than those values of ortho- and meta-type analogs. The observed high rigidity of the ring conformation may induce the extraordinary behaviors in chelation.

there has been a considerable interest in platinum group metal complexes of thiaoxa-donor macrocycles because of their unusual properties. 1 As an extension of our studies involving mixed-donor cyclic 2a and acyclic 2b ligands incorporating thiaoxa mixed-donors, we became interested in exploring their coordination chemistry of platinum group metal ions. The S2O-donor macrocycle of the title com...

متن کاملA flavin-dependent monooxygenase from Mycobacterium tuberculosis involved in cholesterol catabolism.
Mycobacterium tuberculosis (Mtb) and Rhodococcus jostii RHA1 have similar cholesterol catabolic pathways. This pathway contributes to the pathogenicity of Mtb. The hsaAB cholesterol catabolic genes have been predicted to encode the oxygenase and reductase, respectively, of a flavin-dependent mono-oxygenase that hydroxylates 3-hydroxy-9,10-seconandrost-1,3,5(10)-triene-9,17-dione (3-HSA) to a ca...
