Abstract
Survivin, a member of the inhibitor of apoptosis protein family, exists as a homodimer and is aberrantly upregulated in a wide spectrum of cancers. It was thought to be an ideal target due to its lack of expression in most adult normal tissues and importance in cancer cell survival. However, it has been challenging to target survivin due to its "undruggable" nature. We previously attempted to target its dimerization domain with a hypothesis that inhibiting survivin dimerization would promote its degradation in proteasome, which led to identification of a lead small-molecule inhibitor, LQZ-7F. LQZ-7F consists of a flat tetracyclic aromatic core with labile hydrazone linking a 1,2,5-oxadiazole moiety. In this study, we tested the hypothesis that LQZ-7F could be developed as a prodrug because the labile hydrazone linker could be hydrolyzed, releasing the tetracyclic aromatic core. To this end, we synthesized the tetracyclic aromatic core (LQZ-7F1) using reported procedure and tested LQZ-7F1 for its biological activities. Here we show that LQZ-7F1 has a significantly improved potency with submicromolar IC50's and induces spontaneous apoptosis in prostate cancer cells. It also more effectively inhibits survivin dimerization and induces survivin degradation in a proteasome-dependent manner than LQZ-7F. We also show that the combination of LQZ-7F1 and docetaxel have strong synergism in inhibiting prostate cancer cell survival. Together, we conclude that the hydrazone linker with the oxadiazole tail is dispensable for survivin inhibition and the survivin dimerization inhibitor, LQZ-7F, may be developed as a prodrug for prostate cancer treatment and to overcome docetaxel resistance.

Abstract
Survivin, a homodimeric member of the Inhibitor of Apoptosis Protein (IAP) family, is required for cancer cell survival and overexpressed in almost all solid tumors. However, targeting survivin has been challenging due to its "undruggable" nature. Recently, we used a novel approach to target the dimerization interface and identified inhibitors of two scaffolds that can directly bind to and inhibit survivin dimerization. One of the scaffolds, represented by the compound LQZ-7, contains an undesirable labile hydrazone linker and a potentially nonfunctional furazanopyrazine ring that we attempted to eliminate in this study. We found one compound, 7I, that is more active than the parent compound, LQZ-7, and when given orally effectively inhibits xenograft tumor growth and induces survivin loss in tumors. These findings indicate that 7I with a stable linker and a quinoxaline ring can be used as a lead for further optimization of this novel class of survivin inhibitors.

Abstract
We initiated a survey of the Streptococcus pneumoniae genome by DNA sequence sampling. More than 9,500 random DNA sequences of approximately 500 bases average length were determined. Partial sequences sufficient to identify approximately 95% of the aminoacyl tRNA synthetase genes and ribosomal protein (rps) genes were found by comparing the database of partial sequences to known sequences from other organisms. Many genes involved in DNA replication, repair, and mutagenesis are present in S. pneumoniae. Genes for the major subunits of RNA polymerase are also present, as are genes for two alternative sigma factors, rpoD and rpoN. Many genes necessary for amino acid or cofactor biosynthesis and aerobic energy metabolism in other bacteria appear to be absent from the S. pneumoniae genome. A number of genes involved in cell wall biosynthesis and septation were identified, including six homologs to different penicillin binding proteins. Interestingly, four genes involved in the addition of D-alanine to lipoteicoic acid in other gram positive bacteria were found, even though the lipoteicoic acid in S. pneumoniae has not been shown to contain D-alanine. The S. pneumoniae genome contains a number of chaperonin genes similar to those found in other bacteria, but apparently does not contain genes involved in the type III secretion commonly observed in gram negative pathogens. The G+C content of S. pneumoniae genomic DNA is approximately 43 mole percent and the size of the genome is approximately 2.0 Mb as determined by pulsed-field gel electrophoresis. Many of the genes identified by sequence sampling have been physically mapped to the 19 different SmaI fragments derived from the S. pneumoniae genome. The database of random genome sequence tags (GSTs) provides the starting material for determining the complete genome sequence, gene disruption analysis, and comparative genomics to identify novel targets for antibiotic development.
