Synthesis of the C9−C23 (C9′−C23′) Fragment of the Dimeric Natural Product Rhizopodin

Organic Letters, 2010
A stereoselective assembly of the C9-C23 (C9'-C23') fragment of rhizopodin, a 38-membered bis-lactone natural product, has been developed. A highly efficient approach to this fragment assembles >50% of the carbon skeleton and the stereochemical elements present in the natural product.

Synthesis of the C1−C23 Fragment of Spirastrellolide A

Organic Letters, 2008
Synthesis of the C1-C23 fragment in spirastrellolide A is described, featuring a cyclic acetal-tethered RCM for stereoselective constructions of spiroketal, and a 1,3- anti aldol involving methyl ketone enolate and Mukaiyama conditions.

A highly stereoselective synthesis of the C10–C23 fragment of (–)-dictyostatin

open access: yesChemical Communications, 2007
A highly stereoselective synthesis of the C10-C23 fragment of (-)-dictyostatin has been achieved using a Carreira alkynylation and a Marshall-Tamaru allenylzinc addition as key steps.

Immunodominant RNA recognition motifs of human nucleolin/C23

Molecular Immunology, 1995
Nucleolin/C23 is a nucleolar phosphoprotein implicated in the synthesis, processing and transport of ribosomal RNA and gene transcription. Auto-antibodies to human nucleolin/C23 have been reported in patients with systemic lupus erythematosus and other systemic autoimmune disorders.

Localization of nucleolar phosphoproteins B23 and C23 during mitosis

Experimental Cell Research, 1983
Nucleolar phosphoproteins B23 and C23 were simultaneously localized in unsynchronized male rat-kangaroo PtK2 cells during mitosis using a mouse monoclonal antibody against protein B23 and a rabbit antibody against protein C23. The distribution of proteins B23 and C23 during mitosis was compared with the distribution of the silver staining protein ...

Localization of phosphoprotein C23 in nucleoli by immunological methods

Experimental Cell Research, 1981
Abstract Antiserum to a major phosphorylated nucleolar protein. C23 (MW 103000, pI 5.2) from Novikoff hepatoma was produced in rabbits. By immunodiffusion analysis, the antiserum produced precipitin bands and with various crude extracts of nucleoli, but not with extranucleolar or cytosol fractions.
