  Substituted propargylethoxyamido nucleosides are disclosed having the structure ##STR1## wherein X is selected from the group consisting of amino alkanoic acid, alkylamino benzoic acid, .alpha.-amino acid, and 4-amino-2-butynoic acid. R.sub.1 and R.sub.2 taken separately are selected from the group consisting of --H, lower alkyl, protecting group, and label; R.sub.3 is selected from the group consisting of --H and lower alkyl. B is a 7-deazapurine, purine, or pyrimidine nucleoside base. When B is purine or 7-deazapurine, the sugar moiety is attached at the N.sup.9 -position of the purine or deazapurine, and when B is pyrimidine, the sugar moiety is attached at the N.sup.1 -position of the pyrimidine. When B is a purine, the adjacent triple-bonded carbon is attached to the 8-position of the purine, when B is 7-deazapurine, the adjacent triple-bonded carbon is attached to the 7-position of the 7-deazapurine, and when B is pyrimidine, the adjacent triple-bonded carbon is attached to the 5-position of the pyrimidine. W.sub.1 is selected from the group consisting of --H and --OH. W.sub.2 is --OH or a moiety which renders the nucleoside incapable of forming a phosphodiester bond at the 3'-position. W.sub.3 is selected from the group consisting of --PO.sub.4, --P.sub.2 O.sub.7, --P.sub.3 O.sub.10, phosphate analog, and --OH.

  Minor groove binding molecules are covalently bound to oligonucleotides which in their base sequence are complementary to a target sequence of single stranded or double stranded DNA, RNA or hybrids thereof. The covalently bound oligonucleotide minor groove binder conjugates strogly bind to the target sequence of the complementary strand.

• Hybridization and mismatch discrimination using oligonucleotides conjugated to minor groove binders

  Conjugates between a minor groove binding molecule, such as the trimer of 1,2-dihydro-(3H)-pyrrolo[3,2-e]indole-7-carboxylate (CDPI 3 ), and an oligonucleotide form unusually stable hybrids with complementary target sequences, in which the tethered CDPI 3 group resides in the minor groove of the duplex. These conjugates can be used as probes and primers. Due to their unusually high binding affinity, conjugates as short as 8-mers can be used as amplification primers with high specificity and efficiency. MGB conjugation also increases the discriminatory power of short oligonucleotides, providing enhanced detection of nucleotide sequence mismatches by short oligonucleotides. The MGB-conjugated probes and primers described herein facilitate various analytic and diagnostic procedures, such as amplification reactions, PCR, detection of single-nucleotide polymorphisms, gene hunting, differential display, fluorescence energy transfer, hydrolyzable probe assays and others; by allowing the use of shorter oligonucleotides, which have higher specificity and better discriminatory power.

  一种小沟结合分子（例如1,2-二氢-（3H）-吡咯并[3,2-e]吲哚-7-羧酸三聚体（CDPI3））与寡核苷酸之间的共轭体形成具有不寻常稳定性的杂交体，其中锚定的CDPI3基团驻留在双链的小沟中。这些共轭体可用作探针和引物。由于它们的结合亲和力异常高，因此即使是8-mer长度的共轭体也可以用作具有高特异性和高效率的扩增引物。MGB结合还增加了短寡核苷酸的鉴别能力，通过短寡核苷酸提供了更好的核苷酸序列不匹配检测。在此描述的MGB结合的探针和引物可以促进各种分析和诊断程序，例如扩增反应，PCR，单核苷酸多态性检测，基因猎取，差异显示，荧光能量转移，可水解探针测定等，通过允许使用更短的寡核苷酸，这些寡核苷酸具有更高的特异性和更好的鉴别能力。
