Eighteen trifluoroacetyl derivatives of aminoacids and of aminoacidanalogs were prepared and tested for growth-inhibitory activity using a Lactobacillus casei system as a prescreen for antitumor activity. Of the compounds tested, the trifluoroacetyl derivatives of o-, m-, and p-fluorophenylalanine and of beta-3-thienylalanine showed modest activity; trifluoroacetyl derivatives of phenylalanine and of

A modified nucleotide n-mer (where n is an integer of 2 or more) is used which comprises a nucleoside unit with a substituent group introduced into the base, wherein the substituent group is bound to the base via a triple bond. Novel nucleotide oligomers, nucleotide polymers, and nucleosides which can be used as raw materials or intermediates in the synthesis of this nucleotide oligomer and nucleotide polymer, as well as novel techniques for structural determination and manufacture of a functional substance having high affinity for a target, are provided.
This invention describes a new method of constructing double-stranded DNA (dsDNA) microarrays based on the use of pre-synthesized or natural DNA duplexes without a stem-loop structure. The complementary oligonucleotide chains are bonded together by a novel connector that includes a linker for immobilization on a matrix. A non-enzymatic method for synthesizing double-stranded nucleic acids with this novel connector enables the construction of inexpensive and robust dsDNA/dsRNA microarrays. DNA-DNA and DNA-protein interactions are investigated using the microarrays.

The present invention makes available, inter alia, methods and reagents for modulating smoothened-dependent pathway activation. In certain embodiments, the subject methods can be used to counteract the phenotypic effects of unwanted activation of a hedgehog pathway, such as resulting from hedgehog gain-of-function, ptc loss-of-function or smoothened gain-of-function mutations.
