  • Patent number: 8552175
    Abstract: The use of N-formamidino-5-amino-3H-1,2,4-dithiazole-3-thiones, 5-phenyl-3H-1,2,4-dithiazole-3-thiones, and derivatives thereof as novel, efficient sulfur-transfer reagents is disclosed. Sulfur transfer from these reagents to compounds containing a P(III) atom (e.g., triphenylphosphine, 5?-O-DMT-thymidine 2-cyanoethyl-(N,N-diisopropyl)phosphoramidite, and 5?-O-DMT-3?-O-levulinyl dithymidilyl 2-cyanoethyl phosphite), was studied in solution by 31P NMR and HPLC. The sulfur transfer from title compounds was also studied in the solid-phase synthesis of oligonucleotide phosphorothioates by phosphoramidite methods. In this application, the efficiency of the sulfur transfer reaction for 2?-deoxyoligonucleotides was better than 99.5%. The novel sulfurizing agents are synthesized, at low cost, using simple chemical methods.

  • Publication number: 20020010326
    Abstract: In our research, 3-phenyl-1,2,4-dithiazoline-5-one is found to be a potential sulfur-transfer reagent. The efficiency and optimization of this new sulfur-transfer reagent was investigated by solid-phase syntheses of dinucleotide phosphorothioate and 25 mer oligonucleotide phosphorothioates at 1 &mgr;mol and 200 &mgr;mol scales. The results show that 3-phenyl-1,2,4-dithiazoline-5-one is a highly efficient sulfurizing reagent, and greater than 99.8% sulfur transfer efficiency can be achieved. In contrast to EDITH or Beaucage reagent, this novel sulfur-transfer reagent is highly stable in storage and in solution, highly soluble in CH3CN solvent, and can be synthesized at a low cost because of the single step reaction. Due to these advantages, 3-phenyl-1,2,4-dithiazoline-5-one can be considered as a better alternative to EDITH or Beaucage reagent, especially in large-scale preparation of oligonucleotide phosphorothioates.

  • Patent number: 6162791
    Abstract: Novel 1,2,4-thiadiazole compounds are provided, which are effective as inhibitors of cysteine activity-dependent enzymes and in particular of cysteine proteases. The compounds are useful in treating acne by inhibition of transglutaminase, common cold by inhibition of human rhinovirus 3C protease and inflammatory joint disease by inhibition of cathepsins. The compounds of the present invention are 3,5-disubstituted 1,2,4-thiadazole of the general formula (I): ##STR1## where Z is a nitrogen containing group with recognition sequence for the enzyme and Y is a substituent that tunes the reactivity of the inhibitor towards the thiol group of the cysteine activity-dependent enzyme. The Y group may also serve in recognition.

  • Patent number: 6114537
    Abstract: Thiols are trapped, and converted to disulfide compounds, by a process of reacting them with compounds containing a 1,2,4-thiadiazole ring structure carrying a substituent at position 3 of the thiadiazole ring, and being unsubstituted at position N-2. The process is useful pharmacologically, in inhibiting certain thiol-containing enzymes such as H.sup.+ /K.sup.+ -ATPase (the proton pump), and industrially, in selective removal of thiol compounds from gas or liquid mixtures.
