Abstract
A small and structure-biased library of enantiopure anti-β-amino alcohols was prepared in a straightforward manner by a simplified version of the Reetz protocol. Antiproliferative activity testing against a panel of five human solid tumor cell lines gave GI50 values in the range 1-20 μM. The reverse screening by computational methods against 58 proteins involved in cancer pointed to kinases as possible therapeutic target candidates. The experimental determination of the interaction with 456 kinases indicated that the compounds behave as selective CK1ε inhibitors. Our results demonstrate that the lead compound represents the first selective CK1ε inhibitor with proven antiproliferative activity in cancer cell lines.

Abstract
Enantiomerically pure anti-β-amino alcohols were synthesized from optically pure α-(N,N-dibenzylamino)benzyl esters, derived from α-amino acids, by the sequential reduction to aldehyde with DIBAL-H at -78 °C and subsequent in situ addition of Grignard reagents. Besides anti-β-amino alcohols, anti-2-amino-1,3-diols and anti-3-amino-1,4-diols were obtained in good yields (60-95%) and excellent stereoselectivity (de > 95%). Our technique is compatible with free hydroxyl groups present in the substrate. To demonstrate the versatility of the method, spisulosine and sphinganine were synthesized in two steps from the appropriate N,N-dibenzyl-l-aminobenzyl ester in 42% and 45% yield, respectively.

Abstract
The lipidicα-amino acids (LAAs) are non-naturalα-amino acids with saturated or unsaturated long aliphatic side chains. LAAs and their derivatives (lipid mimetics) together with the lipidic peptides represent a class of compounds which combine structural features of lipids with those of amino acids and peptides. Racemic LAAs may be prepared by classical methods and resolved by chemical or enzymatic methods. LAA amides and esters with saturated or unsaturated long chain amines and alcohols respectively, as well as lipidic dipeptide derivatives inhibit both pancreatic and human platelet phospholipase A2. Lipophilic peptide derivatives are inhibitors of human neutrophil elastase. LAAs and their oligomers have been used as drug delivery system. A Lipid-Core-Peptide system has been designed and used as a combined adjuvant-carrier-vaccine system. A variety of lipid mimetics such as lipidic 2-amino alcohols, lipidic 1,2- and 1,3-diamines have been prepared based upon LAAs. Some of them are potent inhibitors of phospholipase A2. A general approach to enantioselective synthesis of LAAs and lipid mimetics is based on the oxidative cleavage of 3-amino-1,2-diols obtained by the regioselective opening of enantiomerically enriched long chain 2,3-epoxy alcohols.

Abstract
A subset of four synthetic sphingoid marine compound analogs was chosen from a preliminary in vitro cytotoxicity study for further analysis. The selected analogs were initially screened in monolayer cultures for their anticancer potential against a panel of eight human tumor cell lines, ovarian, colon and lung cancer, squamous cell carcinoma and leukemia producing IC50 values ranging from 1.5 to 6.9 microM. In a secondary screening, the sphingoid analogs were evaluated against multilayered postconfluent cultures of A2780 ovarian cancer and WiDr colon cancer cells. In this model, compounds 5 and 8 were the most active derivatives showing EC50 values in the range 25-32 microM. The performance of 5 and 8 against both cell lines was not dependent on the cell culture model as shown with resistance factor values in the range 8-12. Cell cycle studies in HL60 leukemia cells showed an arrest in G(0)/G1 at a low drug concentration (3 microM) but accumulation in S phase at a high drug concentration (9 microM). It can be concluded that the analogs showed a cell line independent activity, with an apparent selectivity against cells grown in more physiological three-dimensional condition compared to standard anticancer drugs.

Abstract
Various techniques, namely differential scanning calorimetry, optical microscopy, dielectric and Raman spectroscopy, all covering a wide range of temperatures, were used to study the thermodynamically stable phases and molecular mobility of crystals of long chain 2-amino alcohols. The results showed that two different crystal forms are present in each sample. The temperature behaviour of the phases is studied in details.

Abstract
The synthesis of optically pure long-chain 2-amino-alcohols and 1-O-dodecyl-2-deoxy-2-amino-sn-glycerol was carried out starting from L- or D-Boc-Ser(OBn)-ol by oxidation and consecutive Wittig reaction or etherification reaction. 2-Amino-oleyl alcohol was synthesized by reduction of the corresponding 2-amino-oleic acid. All the long chain amino-alcohols presented interesting inhibition of carrageenin-induced paw edema in rats (ED(50) from 0.017 to 0.010 mmol/kg).

Abstract
An efficient route for the synthesis of enantiopure omega-hydroxy, omega-carboxy, omega-oxo, and omega-amino alpha-amino acids and bis-alpha-amino acids was developed. The synthesis of omega-trityloxy delta,epsilon-unsaturated alpha-amino acids was based on the Wittig reaction of methyl (2S)-2-[bis(tert-butoxycarbonyl)amino]-5-oxopentanoate with omega-trityloxy alkylidene triphenylphosphoranes. After hydrogenation, the omega-hydroxy alpha-amino acid was used as starting material for the synthesis of other omega-functionalized alpha-amino acids. The length of the side chain of alpha-amino acids or bis-alpha-amino acids depends on the starting alkanediol or dibromide used to prepare the phosphoranes.

Abstract
An efficient synthesis of (S)-alpha-amino oleic acid was developed. The fully protected FA derivative was obtained in four steps starting from methyl (2S)-2-[bis(tert-butoxycarbonyl)amino]-5-oxopentanoate. These steps are (i) olefination of the starting aldehyde with the appropriate phosphonate anion, (ii) hydrogenation of the double bonds, (iii) controlled reduction of omega-ethyl ester to an aldehyde in the presence of alpha-methyl ester, and (iv) a Wittig reaction of the latter aldehyde with the suitable ylide. Free alpha-amino oleic acid was prepared after deprotection of the amino group followed by saponification in a total yield of 24%. N-tert-Butoxycarbonyl-protected amino oleic acid and the corresponding amino alcohol were prepared in high yield. The structures of the products have been established by various spectroscopic techniques.

Abstract
Synthetic routes to primary and N-alkyl alpha-keto amides are presented in this paper. Primary alpha-keto amides may be prepared by using an aldehyde as starting material. Commercially available alpha-keto acids may be coupled in high yield with primary amines by the mixed carbonic anhydride method affording N-alkyl alpha-keto amides. Alternatively, N-alkyl alpha-keto amides may be prepared by coupling long-chain alpha-hydroxy acids with amino components, followed by oxidation with pyridinium dichromate or NaOCl in the presence of 4-acetamido-2,2,6,6-tetramethyl-1-piperidinyloxy free radical. The alpha-keto amide derivatives prepared according to these procedures were tested for their ability to form stable monomolecular films at the air/water interface. The inhibition of porcine pancreatic lipase by the alpha-keto amides, spread as mixed films with 1,2-dicaprin, was studied with the monolayer technique. Among the compounds tested in this study, methyl 2-[(2-ketododecanoyl)amino]hexadecanoate was shown to be the most potent inhibitor, causing a 50% decrease in lipase activity at a 0.09 molar fraction.

Abstract
Using a chemo-enzymatic approach we prepared the highly lipophilic, chiral, Calpha-methylated alpha-amino acid (alphaMe)Aun. Two series of terminally protected model peptides containing either D-(alphaMe)Aun in combination with Aib or L-(alphaMe)Aun in combination with Gly were synthesized using solution methods and fully characterized. A detailed solution conformational analysis, based on FT-IR absorption, 1H NMR and CD techniques, allowed us to determine the preferred conformation of this amino acid and the relationship between chirality at its alpha-carbon atom and screw sense of the helix that is formed. The results obtained strongly support the view that D-(alphaMe)Aun favors the formation of the left-handed 3(10)-helical conformation.

Abstract
Lipidic alpha-amino acids (LAAs) are a class of compounds combining structural features of amino acids with those of fatty acids. They are non-natural alpha-amino acids with saturated or unsaturated long aliphatic side chains. Synthetic approaches to optically active LAAs and lipidic 2-amino alcohols (LAALs) are summarized in this review. A general approach to enantioselective synthesis of saturated LAAs is based on the oxidative cleavage of 3-amino-1,2-diols obtained by the regioselective opening of enantiomerically enriched long chain 2,3-epoxy alcohols. Unsaturated LAAs are prepared in their enantiomeric forms by Wittig reaction via methyl (S)-2-di-tert-butoxycarbonylamino-5-oxo-pentanoate. This key intermediate aldehyde is obtained by selective reduction of dimethyl N,N-di-Boc glutamate with DIBAL. (R) or (S) LAALs may be prepared starting from D-mannitol or L-serine. LAAs are converted into LAALs by chemoselective reduction of their fluorides using sodium borohydride with retention of optical purity. Replacement of the hydroxyl group of LAALs by the azido group, followed by selective reduction leads to unsaturated optically active lipidic 1,2-diamines.

Abstract
The synthesis of long chain 3-amino-1,2-diols was carried out based on Sharpless asymmetric epoxidation of long chain allylic alcohols and regioselective nucleophilic ring opening by azido group. The in vitro cytotoxicity of the compounds prepared was evaluated against six solid tumor cell lines (A2780, H322, LL, WiDr, C26-10, UMSCC-22B). Free 3-amino-1,2-diols exhibited IC50 values between 1.45 microM and 32 microM. These compounds also presented interesting inhibition of carrageenin-induced paw edema in rats (85.3% - 79.6% at a concentration of 0.15 mmol/kg).

Abstract
Simple and efficient methods for the synthesis of lipidic amino alcohols and diamines are described in this paper. Lipidic 2-amino alcohols and 1,3-diamines can be synthesized starting from synthetic lipidic alpha-amino acids. Alternatively, commercially available lipidic 1,2-diols may be used as starting material for the synthesis of 2-amino alcohols. Initial experiments on the in vivo antiinflammatory activity of the compounds synthesized gave promising results.
