Abstract: Compounds useful for treating Gram-positive bacterial and mycoplasmal infections are disclosed. The compounds have the general formulae shown below.

Abstract: The invention relates to prodrugs of N-substituted derivatives of 6-aminouracils, 6-aminoisocytosines, guanines, and 2-aminoadenines. The N-linked substituents include an ester group that is cleaved upon administration into a subject to yield a substituent having a terminal hydroxyl group. Pharmaceutical compositions including these compounds, and methods for treating Gram-positive bacterial infections using these compounds, are also disclosed.

Abstract: The invention relates to antimicrobial compounds which interact with zinc in a zinc finger of a bacterial DNA polymerase, methods of screening for such compounds, and methods of using such compounds to inhibit polymerase activity or bacterial growth.

Abstract: The present invention relates to new aminoindane piperidine compounds, the method of using aminoindane compounds as local anesthetics, said compounds having particularly valuable properties as dermal and topical anesthetics in mammals, including man, as well as compositions containing said compounds.

Abstract: Disclosed are N-substituted hydroxyalkyl or carboxyalkyloxyalkyl analogs of 9- and/or 10-oxo-4Hbenzo[4,5]cycloheptal[1,2-b]thiophene compounds, or 9-OH and/or 10-OH-substituted analogs thereof, which possess antihistaminic and antiasthmatic properties with reduced sedative side effects. The optically active isomers and pharmaceutically acceptable salts thereof are also described. The compounds were also found to prevent smooth muscle hyperreactivity.

Abstract: The present invention relates to smooth muscle spasmolytic agents, pharmaceutical compositions containing them and method of using said compounds and compositions for the treatment of urinary incontinence, gastric hyperactivity (ex. Irritable Bowel Syndrome) and other smooth muscle contractile conditions. More particularly, the present invention relates to certain substituted esters, amides and ketones having smooth muscle relaxing properties while avoiding, on administration to a mammal, adverse side effects such as prominent antimuscarinic, arrhythmogenic and cardiodepressive effects.

Abstract: The invention is directed to novel 6-aromatic substituted uracil compounds of formula I therapeutic compositions comprising the compounds, and methods of treating Herpes simplex virus Type I and Type II recurrent infections and Herpes simplex virus Type I and Type II encephalitis in humans using the compounds and/or therapeutic compositions.

Abstract: N.sup.2 -substituted alkylguanine and N.sup.2 -substituted phenylguanine compounds which prevent recurrent herpes simplex infections are disclosed. By virtue of their ability to inhibit herpes virus thymidine kinase in vivo, such compounds will prevent, reduce the frequency of, or reduce the severity of recurring HSV infections in humans. The N.sup.2 -alkylguanine compounds are of the formula: ##STR1## where R.sub.1 is a normal or branched chain C.sub.n H.sub.2n+1 (where n is 1-12); R.sub.2 is H, 2-deoxyribofuranosyl, (CH.sub.2).sub.n OH (where n is 2-5), CH.sub.2 CH(OH)CH.sub.2 OH, (CH.sub.2).sub.n --COOH (where n is 1-4), CH.sub.2 CH(OH)CH.sub.2 --O--COR.sub.4, (CH.sub.2).sub.n --O--COR.sub.4 (where n is 2-5), or (CH.sub.2).sub.n CO--OR.sub.4 (where n is 1-4); R.sub.4 is CH.sub.3, CH.sub.2 CH.sub.3, CH.sub.2 CH.sub.2 NH.sub.2, CH.sub.2 CH.sub.2 N(C.sub.2 H.sub.5).sub.2 or CH.sub.2 CH.sub.2 CO.sub.2 H; and R.sub.3 is OH, H, Cl or NH.sub.2, or a tautomer or a pharmaceutically acceptable salt thereof. The N.

Abstract: New purine compounds having the formula: ##STR1## Y and Y'=H, ##STR2## X=H, alkyl, halo; ##STR3## A=O, S, NH.sub.2 are provided. These compounds are useful in treating patients having cancer, since they are potent and selective inhibitors of replicative DNA synthesis in mammalian cells since they inhibit DNA polymerase .alpha..New purine compounds also are provided having the formula: ##STR4## wherein Y, A, Z are as defined above, X'=C.sub.2 H.sub.5 Y"=--CH.sub.3 or ##STR5## These compounds are useful to prevent bacterial growth since they are potent inhibitors of DNA polymerase III.New Purine compounds also are provided having the formula: ##STR6## wherein Z' is H, OH or CH.sub.2 OH,A' is O of CH.sub.
