Compounds comprisingare disclosed, wherein Y, A, X, R, D, and n are as described.A compound comprising a prostaglandin EP2 selective agonist wherein the ω-chain comprises a substituted phenyl, wherein at least one substituent consists of hydrocarbyl or non-linear hydroxyhydrocarbyl is also disclosed herein.Methods, compositions, and medicaments related thereto are also disclosed.

A method for treating hair loss in mammals uses compositions containing prostaglandin F analogs. The compositions can be applied topically to the skin. The compositions can arrest hair loss, reverse hair loss, and promote hair growth.

Fused cyclopentane—4-substituted 3,5-dioxalane lactone compounds useful as an intermediate in the synthesis of prostaglandin analogs are provided. The compounds have the formula A:wherein R represents an aryl group such as p-methoxyphenyl.This compound can be reacted with a lower alkyl aluminum compound to open the dioxalane ring and reduce the lactone to lactol, without over-reducing to diol. The resulting compound can be functionalized to insert chemical side groups of target prostaglandins, adding the required α-side chain and then the required ω-side chain sequentially and independently of each other. The compounds and process are particularly suitable for preparing lubiprostone.

This invention provides a novel method for the preparation of 2,3-disubstituted -4-oxy-cyclopentan1-one compounds that are useful for the synthesis of prostaglandins and prostaglandin analogs of industrial relevance. The method comprises the metal-catalyzed asymmetric 1,4-conjugate addition of vinylboron compounds to 2-substituted -4-oxy-cyclopent-2-en-1-ones. This method relies on the use of less toxic, easily-handled reagents, and can be performed under milder conditions than offered by some conventional methods, affording 2,3-disubstituted-4-oxy-cyclopentan-1-one compounds enantio- and diastereoselectively, which are precursors to the said prostaglandin and prostaglandin analogs, in high yield.

The present invention relates in general to polymer-bioactive agent conjugates for delivering a bioactive agent to a subject. The polymer-bioactive agent conjugates contain triazole moieties in the polymer backbone and a bioactive moiety selected from prostaglandin analogs, β-blockers and mixtures thereof. The present invention also relates to methods for preparing the polymer conjugates using click chemical reactions, to monomer-bioactive agent conjugates suitable for preparing the polymer conjugates, and to pharmaceutical products comprising the polymer conjugates for the treatment of glaucoma.

The invention provides a method for improving hair biology, e.g., hair growth. The method comprises administering to a subject a monoamine oxidase inhibitor and a vasodilator, a zinc salt of a carboxylic acid, a xanthine compound, pyrithione or a salt thereof, saponin, tritapene, crataegolic acid, celastrol, asiatic acid, an inhibitor of 5-alpha-reductase, 1,4-methyl-4-azasteroid, an androgen receptor antagonist, azelaic acid or a derivate thereof, cyclosporin, triiodothyronine, diazoxide, retinoic acid, a prostaglandin analog, aminexil, carnitine tartrate, apigenin, procapil, or adenosine, in an amount effective to achieve a desired effect. The invention further provides a method of reducing or delaying the appearance of an age-related skin imperfection. The method comprises administering to the subject a composition comprising an MAO inhibitor. A kit for improving hair growth also is provided.
