 Doripenem with cas registry number of 148016-81-3 (formerly S-4661, Shionogi Co., Ltd. Japan) is a novel, broad-spectrum parenteral carbapenem antimicrobial with initial research reports dating from international meetings in 1994. It was launched by Shionogi Co. of Japan under the brand name Finibax in 2005, and is being marketed outside Japan by Johnson & Johnson. Then, on October 12, 2007, Doripenem was approved by the United States Food and Drug Administration. It was allowed to be sold under the tradename Doribax.

 Doripenem (CAS NO.148016-81-3) can be used as an antibacterial agent for bacteria infections.

 Doripenem (CAS NO.148016-81-3) is also known as (+)-(4R,5S,6S)-6-((1R)-1-Hydroxyethyl)-4-methyl-7-oxo-3-(((3S,5S)-5-((sulfamoylamino)methyl)-3-pyrrolidinyl)thio)-1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid ; Doribax ; S 4661 ; S-4661 ; UNII-BHV525JOBH ; 1-Azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 3-(((3S,5S)-5-(((aminosulfonyl)amino)methyl)-3-pyrrolidinyl)thio)-6-((1R)-1-hydroxyethyl)-4-methyl-7-oxo-, (4R,5S,6S)- . Doripenem (CAS NO.148016-81-3) is a chiral reagent with the appearance of white to off-white powder. Doripenem can be soluble in water, slightly soluble in methanol . It is also soluble in N,N-dimethylformamide . It is virtually insoluble in Ethanol . Doripenem is an ultra-broad spectrum injectable antibiotic.
