Abstract: There is disclosed a series of macrolides isolated from the fermentation broth of a microorganism identified as MA-5000 which morphological analysis reveals to be a strain of Streptomyces hygroscopicus. The compound's structure is presented based upon analytical studies. The compound has antifungal activity.

Abstract: There are disclosed certain naphtho-[1,2-b]-quinolizium compounds which have antidiarrheal activity. The compounds reduce fluid accumulation caused by enterotoxins produced by bacteria such as Vibrio cholerae or Escherichia coli.

Abstract: This invention relates to an eyeglass frame mounted unit dose ophthalmic drug delivery device. A unit dose of ophthalmic medicament is provided by either a preloaded disposable microsyringe, preloaded disposable tip or manually loaded calibrated microsyringe rigidly mounted on a block which itself is slidably mounted to the eyeglass frame. The device allows for the insertion of ophthalmic medication into the inferior cul de sac of the eye.

Abstract: A sealing means for a vacuum distillation apparatus is provided having a vapor tube rotatably and sealably mounted within a vacuum tube through which vapor passes.

Abstract: Organic sulfoxides having a latent allyl group bound to the sulfur are enzyme inhibitors of the suicide or K.sub.cat type.

Abstract: Substituted 5-hydroxy-2,3-dihydrobenzofuran and analogs such as the substituted 6-hydroxy-2,3-dihydrobenzopyrans were prepared from an appropriately substituted (5-hydroxy-2,3-dihydrobenzofuran-6-yl) formaldehyde or analog thereof with an aryl amine followed by reduction. These compounds were found to be potent topical anti-inflammatory agents.

Abstract: Eucalyptol is used to enhance skin permeation of bio-affecting agents.

Abstract: There is disclosed a novel combination of avermectin compounds and agricultural spray oil which has been found to be synergistic in such a manner as to allow for a drastic reduction in the amount of active ingredient which is fully effective and also a dramatic extension of the time period over which such a combination is fully effective. The synergistic combination is useful as an agricultural insecticide and miticide against a variety of insects and mites which infest a variety of plants.

Abstract: The invention relates to a device for preparing and dispensing a solution. A bottle containing a substance to be disolved is closed by a disc-shaped base having a rigid rod thereon and a deformable head. A tube of solvent is closed by an apertured slidable piston. Mixing is effected by placing the piston against the rigid rod and applying axial pressure which dispenses the solvent from the tube, through a capillary channel in the rod and into the bottle. Slots in the rod are revealed during this operation to allow the air to escape from the bottle. The deformable head also serves to pressurize the bottle to permit dispensing therefrom.

Abstract: Phenylthiomethyl-6-hydroxy-2,3-dihydrobenzopyran and analogs thereof were prepared from an appropriate (6-hydroxy-2,3-dihydro-benzopyran-7-yl) formaldehyde or analog thereof with a substituted thiophenol. These compounds were found to be potent anti-inflammatory agents.

Abstract: Organic sulfoxides having a latent allyl group bound to the sulfur are enzyme inhibitors of the suicide or K.sub.cat type.

Abstract: Norfloxacin and related antibiotics are useful in the treatment of ocular infections by topical administration.

Abstract: The instant invention is directed to a bioerodible poly(ortho ester) thermoplastic elastomer prepared from:(A) a diketene diacetal;(B) a long-chain non-polar, flexible diol containing 4 to 22 carbon atoms; and(C) a diol selected from the group consisting of:(i) diols containing at least one functional group which produces hydrogen bonding or other association, and(ii) rigid symmetrical diols.

Abstract: There are disclosed novel avermectin and milbemycin compounds wherein the 8a position is oxidized to a ketone group. The 8a-oxo compounds are prepared by oxidizing an avermectin or milbemycin compound. The avermectin and milbemycin 8a-oxo compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests.

Abstract: Substituted cephalosporin sulfones are found to be potent elastase inhibitors and thereby useful anti-inflammatory/antidegenerative agents.

Abstract: Mercaptoalkylpyridines carrying an ethenyl or ethynyl substituent are prepared from known pyridine compounds, principally pyridoxine, by known chemical procedures, and are useful in the treatment of rheumatoid arthritis and related inflammatory diseases.

Abstract: This invention relates to a device for maintaining vessels substantially free of moisture. The device is a cap or stopper having a hollow section to contain a drying agent, a nonporous top member having at least one pinhole therein and a porous bottom member.

Abstract: Novel 2-sulfamoylbenzo[b]furans and derivatives thereof are shown to be useful for the treatment of elevated intraocular pressure in compositions including opthalmic drops and inserts.

Abstract: An improved process for preparing 5-keto-1,3,4,5-tetrahydrobenz[c,d]indole and 6(1H)-oxo-3,4,5,6-tetrahydrocyclohept[c,d]indole is disclosed.

Abstract: 5-[Phenylsulfonyl(or sulfinyl)]thiophene-2-sulfonamides are useful for the topical treatment of elevated intraocular pressure. Ophthalmic compositions including drops and inserts are disclosed.
