The mixed chloro/bromo ?-olefin complexes cis-PtX2(P(t-Bu)2CH2CH2CH=CHCH3) (2) have been prepared by the reaction of Zeise's salt (K) with in boiling ethanol.The dimer complexes (1) (X, Y = Cl or Br) form first with subsequent activation of cyclopropane to give the monomeric ?-olefin complexes (2).The mixed ?-olefin complexes 2 co-crystallize.The average structure of 2 has been determined by X-ray methods.The relative occupancies in bromine for halogen sites cis- and trans- to coordinated olefin are 0.464(6) and 0.256(6), respectively.The olefin is symmetrically bound to the Pt atom (Pt-C 2.17(1) Angstroem).The olefinic C-C bond length is 1.38(1) Angstroem.

A series of 22-hydroxycholesterol derivatives with a modified side chain terminus was prepared.These agents were evaluated in vitro and in vivo for their ability to suppress HMG CoA reductase, the rate-limiting enzyme of cholesterol biosynthesis.In tissue culture assays, 22-hydroxycholesterol as well as the side chain modified analogues were potent inhibitors of HMG CoA reductase.However, only those sterols with a modified side chain terminus were effective suppressors of liver reductase whene administered ig to rats. 22-Hydroxy-25-methylcholesterol (4a) and 25-fluoro-22-hydroxycholesterol (15a) significantly lowered serum cholesterol levels when administered ig to primates; 25-chloro-22-hydroxycholesterol (15b) and the analogue with a cyclopropyl terminus, 20b, were ineffective.The cholesterol-lowering sterols did not significantly alter lipoprotein levels; however, the two compounds have been shown to inhibit acyl-coenzyme A:cholesterol-transferase (ACAT) in tissue culture studies
