Abstract: The present invention describes difluororthioacetamide oxazolidinones of formula I: R is —CH2— or —CH2CH2—; R2 and R3 are independently —H or —F; X is —CH—; Y is —SO—, —SO2—, or —SONR4—; and R4 is —H or —C1-4alkyl. These compounds are useful to treat infectives diseases caused by gram-positive and gram-negative bacteria.

Abstract: The present invention describes difluororthioacetamide oxazolidinones as novel antibacterial agents, and antimicrobial combination therapies for combating infective diseases caused by gram-positive and gram-negative bacteria.

Abstract: The present invention describes difluororthioacetamide oxazolidinones with a glycoloylpiperazine substituent as novel antibacterial agents, and antimicrobial combination therapies for combating infective diseases caused by gram-positive and gram-negative bacteria.

Abstract: The subject invention relates to pyrimidine-thioalkyl and alkylether compounds of Formula I ##STR1## and pyrimidine-thioalkyl and alkylethers of Formula I, where R.sub.4 is selected from the group consisting of --H or --NR.sub.15 R.sub.16 where R.sub.15 is --H and R.sub.16 is --H, C.sub.1 -C.sub.6 alkyl, --NH.sub.2 or R.sub.15 and R.sub.16 taken together with the --N form 1-pyrrolidino, 1-morpholino or 1-piperidino; andR.sub.6 is --S--C.sub.1-6 alkyl (preferably --SCH.sub.3);The compounds of Formula I are useful in the treatment of individuals who are HIV positive.

Abstract: A temperature controlled sample carrier, usable in liquid chromatography apparatus, includes a rotating sample rack having a circumferential array of upward facing sample holes adjacent its periphery for receiving sample vials and orbiting same sequentially past a sampling station. The rack is a solid cylindrical block of heat conducting material which forms a massive heat sink. An insulative cup receives the sample block and rotates therewith. A temperature control device carries a controlled temperature fluid in heat conductive contact with the central portion of the sample block and is overlaid by an insulative cover device which rotates with the block. An insulative cover ring is fixed with respect to the sampling station, overlies the array of sample holes in the block, and extends between the peripheral wall of the cup and the cover device.
