Publication number: 20090180958Abstract: The present invention relates to tumor targeting units comprising a peptide sequence X—R—Y—P—Zn, or a pharmaceutically or physiologically acceptable salt thereof. The invention further relates to tumor targeting agents comprising at least one targeting unit according to the present invention, directly or indirectly coupled to at least one effector unit. The present invention further relates to diagnostic or pharmaceutical compositions comprising at least one targeting unit or at least one targeting agent according to the present invention, and to the use of targeting units or targeting agents according to the present invention for the preparation of a medicament for the treatment of cancer or cancer related diseases, especially for the treatment of non-small cell lung cancer or its metastases.Type: ApplicationFiled: April 25, 2006Publication date: July 16, 2009Applicant: Karyon-CTT Ltd.Inventors: Aki Koivistoinen, Mathias Bergman, Hannu Elo

Publication number: 20080108677Abstract: The present invention relates to thioxothiazolidinone compounds for use as pharmaceuticals, to pharmaceutical compositions comprising these compounds, and to the use of said small-molecule compounds for the manufacture of pharmaceutical compositions for the treatment of conditions dependent on leukocyte cell migration, such as leukaemia and inflammatory diseases. Said compounds inhibit leukaemia cell migration by stabilizing the active conformation of the ?M integrin I domain.Type: ApplicationFiled: August 30, 2005Publication date: May 8, 2008Applicant: Karyon-CTT LtdInventors: Mikael Bjorklund, Erkki Koivunen

Publication number: 20070231258Abstract: The present invention relates to a method for synthesizing peptide conjugates comprising a functional peptide, cyclic by means of a lactam bridge; a sulfur-linker bound to said cyclic peptide, wherein said sulfur-linker comprises sulfur or a sulfur-reactive site. The invention further relates to a method for synthesizing peptide-effector conjugates. The invention also relates to peptide conjugates. Peptide conjugates according to the present invention have improved half-life and increased availability at the active site and they are useful in cell targeting and tumor diagnosis and therapy.Type: ApplicationFiled: March 30, 2007Publication date: October 4, 2007Applicant: KARYON CTT LTD.Inventors: Hannu Perakyla, Merja Huttunen, Eeva-Kaisa Karisalmi, Mathias Bergman, Hannu Elo
