19 mg | Example 3 Dat1-D-Ala2-Asp3-Ala4-Ile5-Phe6-Thr7-Asn8-Ser9-Tyr10-Arg11-Orn12-Val13-Leu14-Abu15-Gln16-Leu17-Ser18-Ala19-Arg20-Orn21-Leu22-Leu23-Gln24-Asp25-Ile26-Nle27-Asp28-Arg29-NH-CH3 (Peptide 27400). [Dat1, D-Ala2, Orn12, Abu15, Orn21, Nle27, Asp28]hGHRH(1-29)NH-CH3 The synthesis is conducted in a stepwise manner using manual solid phase peptide synthesis equipment. Briefly, [3-[(Methyl-Fmoc-amino)methyl]-indol-1-yl]-acetyl AM resin (Nova Biochem, La Jolla, Calif.) (750 mg, 0.50 mmol) is deprotected with 20% piperidine in DMF for 5 and 15 minutes and washed according to the protocol described in Table 3. The solution of Fmoc-Arg(Pbf)-OH (975 mg, 1.5 mmol) in DMF is shaken with the washed resin and DIC (235 muL, 1.5 mmol) in a manual solid phase peptide synthesis apparatus for 1 hour. After washing the resin three times with DMF, the coupling reaction was repeated as described above. After the repeated coupling and after the completion of the reaction is proved by negative ninhydrin test, the deprotection and neutralization protocols described in Table 3 are performed in order to remove the Fmoc protecting group and prepare the peptide-resin for coupling of the next amino acid. The synthesis is continued and the peptide chain is built stepwise by coupling the following protected amino acids in the indicated order on the resin to obtain the desired peptide sequence: Fmoc-Asp(OBut)-OH, Fmoc-Nle-OH, Fmoc-Ile-OH, Fmoc-AspfOBuVOH, Fmoc-Gln(Trt)-OH, Fmoc-Leu-OH, Fmoc-Leu-OH, Fmoc-Orn(Boc)-OH, Fmoc-Arg(Pbf)-OH, Fmoc-Ala-OH, Fmoc-Ser(Trt)-OH, Fmoc-Leu-OH, Fmoc-Gln(Trt)-OH, Fmoc-Abu-OH, Fmoc-Leu-OH, Fmoc-Val-OH, Fmoc-Orn(Boc)-OH, Fmoc-Arg(Pbf)-OH, Fmoc-Tyr(tBu)-OH, Fmoc-Ser(Trt)-OH, Fmoc-Asn(Trt)-OH, Fmoc-Thr(tBu)-OH, Fmoc-Phe-OH, Fmoc-Ile-OH, Fmoc-Ala-OH, Fmoc-AspBu1)-OH, Fmoc-D-Ala-OH, Dat-OH. These protected amino acid residues (also commonly available from Novabiochem, Advanced Chemtech, Bachem, and Peptides International) are represented above according to a well accepted convention. The suitable protecting group for the side chain functional group of particular amino acids appears in parentheses. The OH groups in the above formulae indicate that the carboxyl terminus of each residue is free. The protected amino acids (1.5 mmol each) are coupled with DIC (235 muL, 1.5 mmol) with the exceptions of Fmoc-Asn(Trt)-OH and Fmoc-Gln(Trt)-OH which are coupled with HBTU reagent. In order to cleave the peptide from the resin and deprotect it, a portion of 250 mg of the dried peptide resin is stirred with 2.5 mL cleavage cocktail (94% TFA, 3% H2O, 1.5% m-cresol, and 1.5% phenol) at room temperature for 3 hours. To induce peptide precipitation, the cleavage mixture is added dropwise to cold (preferably -20 C.) ether. The precipitated material is collected by filtration or centrifugation and is washed three times with cold ether. The cleaved and deprotected peptide is dissolved in 50% acetic acid and separated from the resin by filtration. After dilution with water and lyophilization, 118 mg crude product is obtained. The crude peptide is checked by analytical HPLC using a Hewlett-Packard Model HP-1090 liquid chromatograph equipped with a Supelco Discovery HS C18 reversed-phase column (2.1 mm×5 cm, packed with C18 silica gel, 300 pore size, 3 mum particle size) (Supelco, Bellefonte, Pa.). Linear gradient elution (e.g., 40-70% B) is used with a solvent system consisting of (A) 0.1% aqueous TFA and (B) 0.1% TFA in 70% aqueous MeCN, and the flow rate is 0.2 mL/min. Purification is performed on a Beckman System Gold HPLC system (Beckman Coulter, Inc., Brea, Calif.) equipped with 127P solvent Module; UV-VIS Detector, model 166P; Computer workstation with CPU Monitor and printer, and 32-Karat software, version 3.0. 118 mg of crude peptide is dissolved in AcOH/H2O, stirred, filtered and applied on an XBridge Prep OBD reversed phase column (4.6×250 mm, packed with C18 silica gel, 300 A pore size, 5 mum particle size) (Waters Co., Milford, Mass.). The column is eluted with a solvent system described above in a linear gradient mode (e.g., 40-60% B in 120 min); flow rate 12 mL/min. The eluent is monitored at 220 nm, and fractions are examined by analytical HPLC. Fractions with purity higher than 95% are pooled and lyophilized to give 19 mg pure product. The analytical HPLC is carried out on a Supelco Discovery C18 reversed-phase column described above using isocratic elution with a solvent system described above with a flow rate of 0.2 mL/min. The peaks are monitored at 220 and 280 nm. The product is judged to be substantially (>95%) pure by analytical HPLC. Molecular mass is checked by electrospray mass spectrometry, and the expected amino acid composition is confirmed by amino acid analysis. |

The following protected amino acids were coupled: Fmoc-DSer(Trt), Fmoc-Lys(Mtt), Fmoc-DSer(Trt), Fmoc-Ser(Trt), Fmoc-Thr(Trt), Fmoc-Ser(Trt), Fmoc-DSer(Trt), Fmoc-Asp(tBu), Fmoc-DAsp(tBu), Fmoc-Asp(tBu), Fmoc-DAsp(tBu). At each stage the Fmoc group on the growing protected peptide chain was removed by mixing with 20% piperidine in DMF (20 min). The protected peptide resin containing a free N-terminal amino group was mixed with tacrolimus- 32-thiol-3-mercaptoproprionic acid disulfide (150 mg, 0.16 mmol), DIC (3 equiv), and HOBt (3 equiv), and allowed to react overnight and then washed with (0370) dichloromethane. (0371) [00247] The Mtt group on the epsilon amino group of the Lys residue was removed selectively by washing 10 times with a 1.9% solution of trifluoroacetic acid in dichloromethane followed by washing 5 times with N-methylpyrolidone. The resin was then reacted (3 h) with a 3-fold excess of N-maleoyl-b-alanine using an equivalent amount of diisopropylcarbodiimide / HOBT. After washing with dichloromethane, the tacrolimus maleimide peptide was cleaved from the resin and all protecting groups were removed from amino acid side chains by treatment (2 hours) with 10 ml of a mixture of DCM:trifluoroacetic acid:1,3- dimethoxybenzene:triisopropylsilane (6.75:2.5:0.5:0.25). The peptide conjugate was precipitated 3 times with ethyl ether and spun down on centrifuge (3000 rpm). The crude tacrolimus peptide maleimide was purified on silica gel using BAW 4:1:1 (butanol:acetic acid:water). Fractions containing pure compound were collected and lyophilized to yield a white powder. MALDI MS gave a MW of 2199 (see FIG.4C). |

After washing with dichloromethane, the tacrolimus bromoacetamide peptide was cleaved from the resin and all protecting groups were removed from amino acid side chains by treatment (2 hours) with 10 ml of a mixture of DCM:trifluoroacetic acid:1,3-dimethoxybenzene:triisopropylsilane (6.75:2.5:0.5:0.25). The peptide conjugate was precipitated 3 times with ethyl ether and spun down on centrifuge (3000 rpm). The crude tacrolimus peptide (0374) bromoacetamide was purified on silica gel using BAW 4:1:1 (butanol:acetic acid:water). Fractions containing pure compound were collected and lyophilized to yield a white powder. MALDI MS gave a MW of 2169 (JF-19-52; see FIG.4D). |

Fmoc-L-Lys(Boc)-OH (3.34 mmol, 1.567 g) and diisopropylethyl amine (DIPEA, 8.36 mmol, 1.457 mL) in dichloromethane (DCM, 18.58 mL) was added to 2-chlorotrityl resin (1.5 mmol/g, 2.79 mmol, 1.81 g, pre-swelled with DCM) in a Biorad preparative column. The resin was shaken at room temperature (RT) for 18 h. The solvent was removed by filtration, and the solid resin was washed with DCM (5×10 mL) and then dried under vacuum to provide resin 1 (2.713 g, loading 0.81 mmol/g).The resin was swelled with DMF via the Top Wash function (8 mL×10 min) and mixed with a gentle stream of N2 every 30 seconds. The solvent was drained and the resin was washed with a solution of 20% piperidine in N,N-dimethylformamide (DMF, 10 mL×2 over 5 minutes per wash) and mixed with a gentle stream of N2 every 30 seconds. The resin was washed with DMF (15 mL×6 over 60 seconds per wash). The Fmoc protected amino acid was added to the resin (Fmoc-AA, 0.1 M solution in DMF, 3 equiv), followed by HATU (0.2M solution in DMF, 3 equiv.) and N-methyl morpholine (0.8 M in DMF, 5 equiv.). The reaction mixture was then agitated by a gentle stream of nitrogen for 60 min.This standard procedure was used for P4-P1 couplings. After coupling of final P1 amino acid and following the removal of the Fmoc group, the resin was capped with a solution of acetic anhydride/DIPEA/DMF (1:1:3, 5 mL×2 over 10 min). Resin-Fmoc-L-Lys(Boc)-OH (P5)-Fmoc-L-Gly-OH (P4)-Fmoc-L-Ser (Trityl)-OH (P3)-Fmoc-Leu-OH (P2)-Fmoc-Glu-OAll (P1).Resin 2 (0.956 g, 1.0 mmol) was treated with a mixture of 6 DCM (16 ml) and 7 1,1,1,3,3,3-hexafluoro-2-propanol (HFP, 4 ml) and shaken at RT for 10 min. The mixture was filtered, and the filtrate was concentrated in vacuo. The resin was treated with additional DCM (16 ml) and HFP (4 mL) and shaken for 10 min. The mixture was filtered. The combined filtrates were concentrated in vacuo. This material was taken up in DCM and concentrated in vacuo (4×) to provide 8 N2-N-(((S)-4-acetamido-5-(allyloxy)-5-oxopentanoyl)-L-leucyl)-O-trityl-L-serylglycyl-N6-(tert-butoxycarbonyl)-L-lysine.
