Apraglutide TFA (FE 203799 TFA) 是一种合成的33-氨基酸肽和长效的 GLP-2类似物，能够增强全回肠切除的新生短肠综合征小猪的适应性和线性肠生长。
| 生物活性 | Apraglutide TFA (FE 203799 TFA), a synthetic 33-amino-acid peptide and a long-acting GLP-2 analogue, enhances adaptation and linear intestinal growth in a neonatal piglet model of short bowel syndrome with total resection of the ileum[1]. |
体内研究
(In Vivo) | Apraglutide (FE 203799; 5 mg/kg/dose, subcutaneously, twice on days 0 and 4 postsurgery) treated piglets are healthy, have significant lower fecal fat and energy losses and exhibite intestinal lengthening, greater small-intestinal weight, longer villus height, and greater crypt depth on day 7[1].
| Animal Model: | NewbornDuroc piglets, 2-5 days old and weighing between 2-2.6 kg[1]. | | Dosage: | 5 mg/kg/dose. | | Administration: | Subcutaneously, twice on days 0 and 4 postsurgery. | | Result: | On day 7, treated piglets were healthy, had significant lower fecal fat and energy losses and exhibited intestinal lengthening, greater small-intestinal weight, longer villus height, and greater crypt depth. |

| Solvent & Solubility | In Vitro: H2O Peptide Solubility and Storage Guidelines: 1. Calculate the length of the peptide. 2. Calculate the overall charge of the entire peptide according to the following table: | | Contents | Assign value | | Acidic amino acid | Asp (D), Glu (E), and the C-terminal -COOH. | -1 | | Basic amino acid | Arg (R), Lys (K), His (H), and the N-terminal -NH2 | +1 | | Neutral amino acid | Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) | 0 |
3. Recommended solution: | Overall charge of peptide | Details | | Negative (<0) | 1. Try to dissolve the peptide in water first.
2. If water fails, add NH4OH (<50 μL).
3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. | | Positive (>0) | 1. Try to dissolve the peptide in water first.
2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO. | | Zero (=0) | 1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration. |
