Ir/f-Ampha complex catalyzed asymmetric sequential hydrogenation of enones: a general access to chiral alcohols with two contiguous chiral centers.
Li W, Yang T, Song N, Li R, Long J, He L, Zhang X, Lv H. Li W, et al. Chem Sci. 2022 Jan 18;13(6):1808-1814. doi: 10.1039/d1sc05963g. eCollection 2022 Feb 9. Chem Sci. 2022. PMID: 35282638 Free PMC article.
A general and highly efficient method for asymmetric sequential hydrogenation of alpha,beta-unsaturated ketones has been developed by using an iridium/f-Ampha complex as the catalyst, furnishing corresponding chiral alcohols with two contiguous stereocenters in high yields …

Iridium-Catalyzed Asymmetric Hydrogenation of Ketones with Accessible and Modular Ferrocene-Based Amino-phosphine Acid (f-Ampha) Ligands.
Yu J, Long J, Yang Y, Wu W, Xue P, Chung LW, Dong XQ, Zhang X. Yu J, et al. Org Lett. 2017 Feb 3;19(3):690-693. doi: 10.1021/acs.orglett.6b03862. Epub 2017 Jan 17. Org Lett. 2017. PMID: 28093919
A series of tridentate ferrocene-based amino-phosphine acid (f-Ampha) ligands have been successfully developed. The f-Ampha ligands are extremely air stable and exhibited excellent performance in the Ir-catalyzed asymmetric hydrogenation of ketones (full conversions …

Enhanced amphotericin B production by genetically engineered Streptomyces nodosus.
Huang K, Zhang B, Shen ZY, Cai X, Liu ZQ, Zheng YG. Huang K, et al. Microbiol Res. 2021 Jan;242:126623. doi: 10.1016/j.micres.2020.126623. Epub 2020 Oct 13. Microbiol Res. 2021. PMID: 33189073 Free article.
The deletion of the PKS5 gene led to the titer of AmB improved from 5.01 g/L to 6.32 g/L while the by-product amphotericin A (AmA) reduced from 0.51 g/L to 0.12 g/L. A sequence of genes including PKS amphA, acc1, mme and mcm were overexpressed in a deltaPKS5 mutant, result …

Comparative Transcriptome Analysis of Streptomyces nodosus Mutant With a High-Yield Amphotericin B.
Huang K, Zhang B, Chen Y, Liu ZQ, Zheng YG. Huang K, et al. Front Bioeng Biotechnol. 2021 Feb 1;8:621431. doi: 10.3389/fbioe.2020.621431. eCollection 2020. Front Bioeng Biotechnol. 2021. PMID: 33598451 Free PMC article.
One of the competitive secondary metabolites of the polyketone synthetase (PKS) II type sapromomycin analog synthesis gene cluster was downregulated, which competes for malonyl-CoA. Five PKS modules (except for the first module amphA) of the amphotericin synthetic gene clu …

Plasma arginine esterase in cystic fibrosis: kinetics of activation, identification as plasma kallikrein, reaction with alpha 2-macroglobulin and comparison with levels in normal plasma.
Bury AF, Barrett AJ. Bury AF, et al. Pediatr Res. 1982 Aug;16(8):613-20. doi: 10.1203/00006450-198208000-00006. Pediatr Res. 1982. PMID: 6180371
The activity ran in gel chromatography with alpha 2 macroglobulin (ampha 2M), as if it were due to an alpha 2M proteinase complex. The generation of the arginine esterase activity by chloroform and ellagic acid was apparently dependent on the activation of factor XII, bein …

Desymmetrization of cyclic 1,3-diketones via Ir-catalyzed hydrogenation: an efficient approach to cyclic hydroxy ketones with a chiral quaternary carbon.
Gong Q, Wen J, Zhang X. Gong Q, et al. Chem Sci. 2019 May 21;10(25):6350-6353. doi: 10.1039/c9sc01769k. eCollection 2019 Jul 7. Chem Sci. 2019. PMID: 31341590 Free PMC article.
We herein report an efficient method to synthesize cyclic hydroxy ketones with a chiral quaternary center. Catalyzed by an Ir/f-ampha complex, cyclic alpha,alpha-disubstituted 1,3-diketones were hydrogenated, giving mono-reduced products with both high enantioselectivities …

Thyrotropin-releasing hormone and amphetamine produce different patterns of behavioral excitation in rats.
Ervin GN, Schmitz SA, Nemeroff CB, Prange AJ Jr. Ervin GN, et al. Eur J Pharmacol. 1981 Jun 10;72(1):35-43. doi: 10.1016/0014-2999(81)90294-6. Eur J Pharmacol. 1981. PMID: 6790295
Both TRH and low amph. increased grooming (perhaps simply by increasing wakefulness), but TRH failed to increase sniffing, a cardinal feature of ampha.-induced excitement. Unlike amph., TRH produced wet-dog shakes, piloerection, tail elevation and teeth chattering. ...
