Drug Information
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection. (See all compounds classified as Anti-Infective Agents.)|Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)|Drugs that are pharmacologically inactive but when exposed to ultraviolet radiation or sunlight are converted to their active metabolite to produce a beneficial reaction affecting the diseased tissue. These compounds can be administered topically or systemically and have been used therapeutically to treat psoriasis and various types of neoplasms. (See all compounds classified as Photosensitizing Agents.)|Pesticides designed to control insects that are harmful to man. The insects may be directly harmful, as those acting as disease vectors, or indirectly harmful, as destroyers of crops, food products, or textile fabrics. (See all compounds classified as Insecticides.)
2,2,5,2''-terthiophene
2,2′:5′,2′′-Terthiophene Use and Manufacturing
To the cyclohexane solution was added 1 mmol of thiophene tetrahydrofuran solution, Under nitrogen protection, 4 equivalents of 2.6 mol / L of butyllithium were added dropwise at -78 C.Stirring was continued for 1 hour, Then put 4 equivalentsDibromoethaneWas added to the reaction solution.The reaction temperature rose to room temperature, Continue to react for 12 hours.The reaction was then quenched with 10 mL of water, The organic phase was extracted with ether.The mixed organic phases were washed with saturated brine, Dried with MgS04, The organic phase was concentrated by decompression.Column separation (cyclohexane / dichloromethane 10: 1 to 5: 1).To give 2- (4-bromobutyl) -5- (5- (2-thienyl) 2-thienyl) thiophene as white crystals
Monomer precursors of polythiophene, photosensitizers, polycarbonate dopants; phototoxic nematicides and antibiotics present in marigolds, when irradiated under aerobic conditions, will produce singlet oxygen with UV enhancement Antibacterial activity
