-
Paragraph 0407-0408, (2018/08/25)
The present disclosure generally relates to modified relaxin polypeptides, such as modified human relaxin 2 polypeptides, comprising a non-naturally encoded amino acid which is linked to a pharmacokinetic enhancer, and therapeutic uses of such polypeptides, such as for the treatment of cardiovascular conditions (such as heart failure) and/or conditions relating to fibrosis.
A process for preparing a fatty acid derivative method and its application (by machine translation)
-
Paragraph 0112-0114, (2018/04/01)
The invention discloses a method for preparing a fatty acid derivative method and its application. The first method is the long-chain fatty acid and thionyl chloride reaction, to obtain the acyl chloride; acyl chloride of preparing butanol reaction, then remove chlorine group, and get long-chain fatty acid uncle ding zhi; then and N - hydroxysuccinimide reaction, long-chain fatty acid succinimide and high yield butylacrylate; then with the L - glutamic acid - 1 - tert-butyl reaction, to obtain tert-butyl long-chain fatty acyl - L - Glu - OtBu; with the N - hydroxysuccinimide reaction, to obtain tert-butyl long-chain fatty acyl - L - Glu (OSu)- OtBu; finally [...] butyl long-chain fatty acyl - L - Glu (OSu)- OtBu tert-butyl in removing, and get long-chain fatty acid derivatives. The method routes the operation is simple, quality is controllable, is suitable for industrial production, and low cost, simple purification at the same time, suitable for use in the preparation of high purity insulin analogs.

Trigger lipids inducing pH-dependent liposome fusion

Aspartic acid-derived artificial lipids (ADLs; s indicates the number of the methylene groups, s=2, 4, 6, 8, 10, 12) (Scheme 1) with various carboxyl alkyl chains as head groups are designed and synthesized, which are incorporated into liposome membranes by sonication. Fluorescence resonance energy transfer (FRET) measurements indicate that ADL6, ADL8 and ADL10 have high lipid-mixing ability in the acidic solution. The other ADLs, however, do not induce remarkable liposome fusion at acidic nor neutral pH. The hydrophobicity of the head groups of ADL6, ADL8 and ADL10 is suitable as triggers of membrane fusion.

, p. 823 - 824 (2007/10/03)
Liposomes including aspartic acid-derived artificial lipids (ADL) with various carboxy alkyl chains as head groups (ADLn; n indicates the number of the methylene groups, n = 2,4,6,8,10,12) are prepared, in which ADL6 and ADL8 liposomes induce remarkably high lipid-mixing in the acidic region.
