Reference to a compound of Formula (I) herein is understood to include reference to salts thereof, unless otherwise indicated. The term “salt(s)”, as employed herein, denotes acidic salts formed with inorganic and/or organic acids, as well as basic salts formed with inorganic and/or organic bases. In addition, when a compound of Formula (I) contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions (“inner salts”) may be formed and are included within the term “salt(s)” as used herein. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the Formula (I) may be formed, for example, by reacting a compound of Formula (I) with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization. 
     Exemplary acid addition salts include acetates, ascorbates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, fumarates, hydrochlorides, hydrobromides, hydroiodides, lactates, maleates, methanesulfonates, naphthalenesulfonates, nitrates, oxalates, phosphates, propionates, salicylates, succinates, sulfates, tartarates, thiocyanates, toluenesulfonates (also known as tosylates,) and the like. Additionally, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are discussed, for example, by P. Stahl et al, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use. (2002) Zurich: Wiley-VCH; S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(1) 1-19; P. Gould, International J. of Pharmaceutics (1986) 33 201-217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (Food &amp; Drug Administration, Washington, D.C. on their website). These disclosures are incorporated herein by reference thereto. 
     Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases (for example, organic amines) such as dicyclohexylamines, t-butyl amines, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g. methyl, ethyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, and dibutyl sulfates), long chain halides (e.g. decyl, lauryl, and stearyl chlorides, bromides and iodides), aralkyl halides (e.g. benzyl and phenethyl bromides), and others. 
     All such acid salts and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention. 
     Compounds of Formula (I), and salts, solvates and prodrugs thereof, may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present invention. 
     All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates and prodrugs of the compounds as well as the salts and solvates of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this invention, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms “salt”, “solvate” “prodrug” and the like, is intended to equally apply to the salt, solvate and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds. 
     Polymorphic forms of the compounds of Formula (I), and of the salts, solvates and prodrugs of the compounds of Formula (I), are intended to be included in the present invention. 
     The compounds according to the invention have pharmacological properties; in particular, the compounds of Formula (I) can inhibit gamma-secretase, and are therefore useful in the treatment or prevention of neurodegenerative diseases, e.g., Alzheimer&#39;s Disease. 
     Representative compounds of the invention include but are not limited to the compounds and Examples described herein. 
     Pharmaceutical compositions can comprise one or more of the compounds of Formula (I). For preparing pharmaceutical compositions from the compounds described by this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may be comprised of from about 5 to about 95 percent active compound. Suitable solid carriers are known in the art, e.g. magnesium carbonate, magnesium stearate, talc, sugar or lactose. Tablets, powders, cachets and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and methods of manufacture for various compositions may be found in A. Gennaro (ed.), Remington&#39;s Pharmaceutical Sciences, 18th Edition, (1990), Mack Publishing Co., Easton, Pa., herein incorporated by reference in its entirety. 
     Liquid form preparations include solutions, suspensions and emulsions. Water or water-propylene glycol solutions for parenteral injection or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions are examples. Liquid form preparations may also include solutions for intranasal administration. 
     Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g. nitrogen. 
     Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions. 
     The compounds of the invention may also be deliverable transdermally. The transdermal compositions can take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose. 
     Preferably, the pharmaceutical preparation is in a unit dosage form. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active compound, e.g., an effective amount to achieve the desired purpose. 
     The term “pharmaceutical composition” is also intended to encompass both the bulk composition and individual dosage units comprised of more than one (e.g., two) pharmaceutically active agents such as, for example, a compound of the present invention and an additional agent selected from the lists of the additional agents described herein, along with any pharmaceutically inactive excipients. The bulk composition and each individual dosage unit can contain fixed amounts of the afore-said “more than one pharmaceutically active agents”. The bulk composition is material that has not yet been formed into individual dosage units. An illustrative dosage unit is an oral dosage unit such as tablets, pills and the like. Similarly, the herein-described method of treating a patient by administering a pharmaceutical composition of the present invention is also intended to encompass the administration of the afore-said bulk composition and individual dosage units. 
     The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.01 mg to about 1000 mg, preferably from about 0.01 mg to about 750 mg, more preferably from about 0.01 mg to about 500 mg, and most preferably from about 0.01 mg to about 250 mg, according to the particular application. The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage regimen for a particular situation is within the skill of the art. For convenience, the total daily dosage may be divided and administered in portions during the day as required. 
     The amount and frequency of administration of the compounds of the invention and/or the pharmaceutically acceptable salts thereof will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 0.04 mg/day to about 4000 mg/day, in one to four divided doses. 
     EXAMPLES 
     The invention disclosed herein is exemplified by the following preparations and examples, which should not be construed to limit the scope of the disclosure. Alternative mechanistic pathways and analogous structures will be apparent to those skilled in the art. 
     The deuterated compounds of this invention can be made according to procedures well known in the art, and by the procedures described below. The deuterated compounds of this invention can be made by substituting the appropriate deuterated reagents in the procedures described in WO2009/008980 published Jan. 15, 2009, the disclosure of which is incorporated herein by reference thereto. 
     Deuterium can be incorporated into various positions in place of hydrogen using the methods described for making the hydrogen compounds. For instance, reducing agents such as lithium aluminum hydride, sodium borohydride, and hydrogen gas can be replaced by lithium aluminum deuteride, sodium borodeuteride, and deuterium gas to introduce deuterium in the same manner as hydrogen. In addition, other reagents used to prepare the hydrogen compounds can be prepared in deuterated form from appropriate deuterated precursors. For instance, a deuterated Grignard reagent can be prepared from the appropriate deuterated alkyl or aryl halide in the same manner as the undeuterated reagent. Similarly, deuterated alkyl and aryl thiols, sulfinic acids, sulfenic acids, sulfoxides, and sulfones can be prepared using well known reagents and used in the methods previously described for making hydrogen compounds. One skilled in the art will recognize that there are also additional methods for introducing deuterium. For instance, hydrogen can be replaced by halogen using well known halogenation conditions (eg halogen or N-halosuccinimide optionally in the presence of a lewis acid, light, or radical initiator) followed by reductive dehalogenation using deuterium gas or metal deuteride. One skilled in the art will also recognize that where any of these methods has the potential to introduce multiple deuteriums at different points on the molecule, there may be an unequal incorporation of deuterium depending on the specific reagents and substrates used and all potential sites of deuteration may not be deuterated. 
     The deuterated compounds of this invention would be prepared by following the methods in the table below. Methods 1 to 7 are described below the table. The Schemes referred to in Methods 1 to 7 are disclosed in WO2009/008980 published Jan. 15, 2009.

     Assay 
     The pharmacological properties of the compounds of this invention may be evaluated by a number of pharmacological assays. Gamma secretase activity can be determined by the assay described below. 
     Gamma-secretase activity is determined as described by Zhang et al. (Biochemistry, 40 (16), 5049-5055, 2001), which is herein incorporated by reference. Activity is expressed either as a percent inhibition or as the concentration of compound producing 50% inhibition of enzyme activity. 
     Reagents. 
     Antibodies WO2, G2-10, and G2-11 are obtained from Dr. Konrad Beyreuther (University of Heidelberg, Heidelberg, Germany). WO2 recognizes residues 5-8 of Aβ peptide, while G2-10 and G2-11 recognize the specific C-terminal structure of Aβ 40 and Aβ 42, respectively. Biotin-4G8 is purchased from Senetec (St. Louis, Mo.). All tissue culture reagents to be used in this work are from Life Technologies, Inc., unless otherwise specified. Pepstatin A is purchased from Roche Molecular Biochemicals; DFK167 is from Enzyme Systems Products (Livermore, Calif.). 
     cDNA Constructs, Tissue Culture, and Cell Line Construction. 
     The construct SPC99-Ion, which contains the first 18 residues and the C-terminal 99 amino acids of APP carrying the London mutation, has been described (Zhang, L., Song, L., and Parker, E. (1999) J. Biol. Chem. 274, 8966-8972). Upon insertion into the membrane, the 17 amino acid signal peptide is processed, leaving an additional leucine at the N-terminus of Aβ. SPC99-lon is cloned into the pcDNA4/TO vector (Invitrogen) and is transfected into 293 cells which are stably transfected with pcDNA6/TR, which is provided in the T-REx system (Invitrogen). The transfected cells are selected in Dulbecco&#39;s modified Eagle&#39;s media (DMEM) supplemented with 10% fetal bovine serum, 100 units/mL penicillin, 100 g/mL streptomycin, 250 g/mL zeocin, and 5 g/mL blasticidin (Invitrogen). Colonies are screened for Aβ production by inducing C99 expression with 0.1 g/mL tetracycline for 16-20 h and analyzing conditioned media with a sandwich immunoassay (see below). One of the clones, designated as pTRE.15, is used in these studies. 
     Membrane Preparation. 
     C99 expression in cells is induced with 0.1 g/mL tetracycline for 20 h. The cells are pretreated with 1 M phorbol 12-myristate 13-acetate (PMA) and 1 M brefeldin A (BFA) for 5-6 h at 37 C before harvesting. The cells are washed 3 times with cold phosphate-buffered saline (PBS) and are harvested in buffer A containing 20 mM Hepes (pH 7.5), 250 mM sucrose, 50 mM KCl, 2 mM EDTA, 2 mM EGTA, and Complete protease inhibitor tablets (Roche Molecular Biochemicals). The cell pellets are flash-frozen in liquid nitrogen and stored at −70° C. before use. 
     To make membranes, the cells are resuspended in buffer A and are lysed in a nitrogen bomb at 600 psi. The cell lysate is centrifuged at 1500 g for 10 min to remove nuclei and large cell debris. The supernatant is centrifuged at 100000 g for 1 h. The membrane pellet is resuspended in buffer A plus 0.5 M NaCl, and the membranes are collected by centrifugation at 200000 g for 1 h. The salt-washed membrane pellet is washed again in buffer A and centrifuged at 100000 g for 1 h. The final membrane pellet is resuspended in a small volume of buffer A using a Teflon-glass homogenizer. The protein concentration is determined, and membrane aliquots were flash-frozen in liquid nitrogen and stored at −70° C. 
     γ-Secretase Reaction and Aβ Analysis. 
     To measure γ-secretase activity, membranes are incubated at 37° C. for 1 h in 50 μL of buffer containing 20 mM Hepes (pH 7.0) and 2 mM EDTA. At the end of the incubation, Aβ 40 and Aβ 42 are measured using an electrochemiluminescence (ECL)-based immunoassay. Aβ 40 is identified with antibody pairs TAG-G2-10 and biotin-WO2, while Aβ 42 is identified with TAG-G2-11 and biotin-408. The ECL signal is measured using an ECL-M8 instrument (IGEN International, Inc.) according to the manufacturer&#39;s instructions.
