Abstract
Metal-catalyzed trans-1,2-hydrosilylations and hydroborations of terminal alkynes that generate synthetically valuable (Z)-alkenylsilanes and (Z)-alkenylboranes remain challenging due to the (E)-selective nature of the reactions and the formation of the thermodynamically unfavorable (Z)-isomer. The development of new, efficient catalytic systems for the (Z)-selective hydrosilylation and hydroboration of terminal alkynes is thus highly desirable from a fundamental perspective as it would deepen our understanding of the metal-catalyzed (Z)-selective hydrosilylation and hydroboration of terminal alkynes. This personal account describes our research for developing a ruthenium complex that can efficiently catalyze the hydrosilylation and hydroboration of terminal alkynes, and for exploring the factors controlling (Z)-selectivity of the reactions. Our effort into the activation of B-protected boronic acids, R-B(dan) (dan=naphthalene-1,8-diaminato), that was believed not to participate in Suzuki-Miyaura cross-coupling, is also discussed.

Abstract
Phosphatidylinositol-4-phosphate (PI(4)P) is an important regulator of Golgi function. Metabolic regulation of Golgi PI(4)P requires the lipid phosphatase Sac1 that translocates between endoplasmic reticulum (ER) and Golgi membranes. Localization of Sac1 responds to changes in glucose levels, yet the upstream signaling pathways that regulate Sac1 traffic are unknown. Here, we report that mitogen-activated protein kinase (MAPK) Hog1 transmits glucose signals to the Golgi and regulates localization of Sac1. We find that Hog1 is rapidly activated by both glucose starvation and glucose stimulation, which is independent of the well-characterized response to osmotic stress but requires the upstream element Ssk1 and is controlled by Snf1, the yeast homolog of AMP-activated kinase (AMPK). Elimination of either Hog1 or Snf1 slows glucose-induced translocation of Sac1 lipid phosphatase from the Golgi to the ER and thus delays PI(4)P accumulation at the Golgi. We conclude that a novel cross-talk between the HOG pathway and Snf1/AMPK is required for the metabolic control of lipid signaling at the Golgi.

Abstract
Toward the objective of designing a structurally modified analogue of the combretastatin A-4 phosphate prodrug (1b) with the potential for increased specificity toward thyroid carcinoma, synthesis of a series of iodocombstatin phosphate (11a-h) and diiodocombstatin phosphate prodrugs (12a-h) has been accomplished. The diiodo series was obtained via 8a and 9c from condensation of 4 and 6, and the iodo sequence involved a parallel pathway. Both series of iodocombstatins were found to display significant to powerful inhibition of the growth of a panel of human cancer cell lines and of the murine P388 lymphocytic leukemia cell line. Of the diiodo series, 12a was also found to markedly inhibit growth of pediatric neuroblastoma, and monoiodocombstatin 9a strongly inhibited HUVEC growth. Overall, the strongest activity was found against the breast, CNS, leukemia, lung, and prostate cancer cell lines and the least activity against the pancreas and colon lines. Parallel biological investigations of tubulin interaction, antiangiogenesis, and antimicrobial effects were also conducted.
