Valacyclovir, a potential prodrug for the treatment of patients with herpes simplex and herpes zoster, and its analogs were resolved on two chiral stationary phases (CSPs) based on (3, 3′-diphenyl-1, 1′-binaphthyl) -20-crown-6 covalently bonded to silica gel. The conjugate of any of claims 1-7, wherein X and Y are S. 10. The conjugate of any of claims 1-21, wherein the drug is selected from cidofovir (CDV) , idoxuridine (IDU) , vidarabine (adenine arabinoside, ara-A) , trifluridine (trifluorothymidine) , acyclovir, famciclovir penciclovir, valacyclovir, ganciclovir, foscarnet, ribavirin, amantadine and rimantadine. Such chiral centers may be of either the (R) or (S) configuration, or may be a mixture thereof. The method of claim 1, wherein at least one of X1 or X2 is N, S, O, SO2, or NR8, is enantiomerically pure) , and an optically pure compound having more than one chiral center is one that is both diastereomerically pure and enantiomerically pure. 128 Antiviral agents include abacavir, aciclovir, acyclovir, adefovir, amantadine, amprenavir, arbidol, atazanavir, atripla, brivudine, cidofovir, combivir, darunavir, delavirdine, didanosine, docosanol, edoxudine, efavirenz, emtricitabine, enfuvirtide, entecavir, famciclovir, fomivirsen, fosamprenavir, foscarnet, fosfonet, ganciclovir, gardasil, ibacitabine, imunovir, idoxuridine, imiquimod, indinavir, inosine, lamivudine, lopinavir, loviride, maraviroc, nelfmavir, nevirapine, nexavir, oseltamivir, penciclovir, peramivir, pleconaril, podophyllotoxin, ribavirin, rimantadine, ritonavir, saquinavir, stavudine, tenofovir, tenofovir disoproxil, tipranavir, trifluridine, trizivir, tromantadine, truvada, valaciclovir, valganciclovir, vicriviroc, vidarabine, viramidine, zalcitabine, zanamivir, zidovudine, and the like.

Liquid Chromatographic Resolution Of Amino Acid Esters Of Acyclovir Including Racemic Valacyclovir On Crown Ether-based Chiral Stationary Phases

Center renders the molecule chiral atom holding a set of. Ibuprofen, is sold as a its mirror image An example. A potential For example, s-ibuprofen everyday life ibuprofen Are two. Enantio-separation of drugs with multiple chiral centers by chromatography and capillary electrophoresis Zeid A. The utilization of L-valine for its chiral centre is increasing in the fine chemical, biologic, and pharmaceutical sectors. M. Curran and S. Noble, Drugs, 2001, 61, 1145; (c).

Diastereomers were synthesized using a new monochloro-s-triazine-based chiral derivatizing reagent (CDR) , namely, N- (4-chloro-6-piperidinyl-1, 3, 5-triazine-2-yl) -L-phenylalanine, under microwave irradiation. Liquid Chromatographic Resolution of Amino Acid Esters of Acyclovir Including Racemic Valacyclovir on Crown Ether-Based Chiral Stationary Phases. Bond valence sum (BVS) calculations and the Jahn-Teller effect indicate that the Mn centers are in a +3 oxidation state. Among other things, for use in directional motion of chiral objects in a mixture, a field is applied across the chamber and is rotating relative to the chamber to cause rotation of the chiral objects. A stereoisomer includes at least one stereocenter, which is any atom that bears groups such that an interchanging of any two groups leads to a stereoisomer. For example, for a molecule with 3 stereocenters (e. g. S, S, S) , its enantiomer would be (R, R, R) ; epimers are stereoisomers that differ in only one but not all stereocenters (e.

Valacyclovir hydrochloride. 1996). -Lactams also have a chiral center and therefore exist both as D- and L-forms. (PepT1) -mediated uptake of a nonpeptide prodrug, valacyclovir. Valacyclovir, a potential prodrug for the treatment of patients with herpes simplex and herpes zoster, and its analogs were resolved on two chiral stationary phases (CSPs) based on (3, 3′-diphenyl-1, 1′-binaphthyl) -20-crown-6 covalently bonded to silica gel. In a randomized, open-label, single-center trial, recipients of renal transplants (recipient or donor cytomegalovirus-seropositive) were randomly allocated (1: 1) to 3-month prophylaxis with valacyclovir (2 g four times daily) or valganciclovir (900 mg daily).
