The discovery of this venom-derived peptide led to a series of structural, mechanistic and pharmacological studies directed towards the development of a new analgesic for neuropathic pain by groups in Australia and internationally. Solid-phase peptide synthesis played an important role in developing structure–activity relationships. Studies in a rat model of neuropathic pain showed that a cyclic analogue of the peptide, cVc1.1, had comparable analgesic activity with that of gabapentin, one of the foremost clinically used drugs for neuropathic pain, with cVc1.1 delivered orally at a 120-fold lower dose than gabapentin. Originally, Vc1.1 was believed to act primarily through nicotinic acetylcholine receptors, but evidence for a mechanism mediated through γ-aminobutyric acid B (GABAB) receptors later emerged. Efforts to optimise the binding and pharmacological properties of analogues of Vc1.1 revealed that the affinity towards either receptor can be modulated by sequence mutations, disulfide bond modifications and backbone cyclisation. This Account describes the discovery, structure, chemistry and pharmacology of Vc1.1, with a focus on studies carried out in Australian laboratories.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135953869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tests include reaction energies and barriers in mechanisms of catalysis, and binding of substrates with enzyme active sites. Drawbacks of the CP approach include: it is more costly than calculations with the same basis set without applying CP corrections, multiple computations may be required where a single species is used in multiple instances, and it is only applicable to intermolecular interactions. In comparison, using gCP or vDZP is less costly. Their overall accuracy is comparable to CP, although the three approaches show variable performances for different systems. Thus, the use of a large basis set remains more consistent in obtaining results that are closer to the basis-set limit. Where the computational cost poses a challenge, the use of gCP or vDZP would be more advantageous than CP in terms of cost and simplicity.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, researchers of super-wetting materials pay more attention to the research and development of responsive materials. Here, a thermal and magnetic dual-responsive superhydrophilicity/underwater superoleophobicity switchable device (Fe3O4@PNIPAM-Cu) was simply fabricated using the Fe3O4 nanoparticles, poly-N-isopropylacrylamide (PNIPAM) hydrogel as the functional coating and copper foam as the skeleton through a one-step solution immersion method. The separation efficiency of the benzene-water mixture of this dual-responsive device can reach up to 99.98%. Even after 10 separation cycles, it maintained an efficiency of more than 99.90%. At temperatures above ~34°C, the device can stop oil–water separation. The experiments presented here demonstrate this dual-responsive device possesses excellent superhydrophilicity/underwater superoleophobicity, thermal-responsive property and magnetic navigation function.","PeriodicalId":8575,"journal":{"name":"Australian Journal of Chemistry","volume":"39 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84437877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
