Abstract
Concentrations reported for indolic microbial metabolites of tryptophan in human and rodent brain, cerebrospinal fluid, plasma, saliva and feces were compiled and discussed. A systematic review of the literature was accomplished by key word searches of Pubmed, Google Scholar and the Human Metabolome Data Base (HMDB), and by searching bibliographies of identified publications including prior reviews. The review was prompted by the increasing appreciation of the physiological importance of the indolic compounds in human health and disease. The compounds included were indoleacetic acid (IAA), indole propionic acid (IPA), indoleacrylic acid (IACR), indolelactic acid (ILA) indolepyruvic acid (IPY), indoleacetaldehyde (IAALD), indolealdehyde (IALD), tryptamine (TAM), indole (IND) and skatole (SKT). The undertaking aimed to vet and compare existing reports, to resolve apparent discrepancies, to draw biological inferences from the consideration of multiple analytes across sample types, to survey the analytical methodologies used, and to point out areas in need of greater attention.

Drug Metab Pharmacokinet 2021; 40:100406.

Abstract
Carbapenem antibiotics are excreted preferentially in the urine after intravenous administration, with organic anion transporters (OATs) known to be involved in the renal tubular secretion of carbapenem antibiotics. Various uremic toxins (UTs) accumulate in the blood of patients with end-stage renal failure, and some UTs such as indoxyl sulfate (IS) and creatinine (Cr) are excreted in the urine via OATs. However, information about the possible interactions between these UTs and carbapenems in the renal secretion remains limited. In this study, we investigated the effects of IS and Cr on the renal transport of anionic meropenem and zwitterionic biapenem by using rat renal cortical slices. The uptake of meropenem and biapenem in the renal cortical slices was significantly decreased in the presence of 0.1 mM IS or 1 mM Cr. When biapenem and Cr were co-administered to rats intravenously, biapenem clearance from the plasma was clearly retarded, reflecting the current in vitro results. However, IS and Cr exerted no inhibitory effect on the uptake of metformin, a substrate of renal organic cation transporter (OCT) 2, in the renal cortical slices. Thus, our findings indicate that IS and Cr interfere with the renal secretion of carbapenem antibiotics by preferentially inhibiting OATs.

Abstract
The accumulation of uremic toxins in blood might induce chronic renal failure (CRF). The incidence of CRF was as high as 10%. The traditional therapy for CRF was hemodialysis, which was more effective to remove small molecules, such as urea and creatinine. However, this detoxification method ignored the tissue functional adaption due to the retention of macromolecule uremic toxins. To solve this problem, this paper developed a new kind of chitosan/carboxyl graphite oxide (CS/GO-COOH) scaffold via a double-lyophilization method. Then, this synthetic scaffold was characterized by Fourier transform infrared spectroscopy, scanning electron microscope, hydrophilic test, mechanical property, and in vitro detoxification test. Covalent bonding and hydrogen bonding were formed, indicating the strong interactions between CS and GO-COOH. There were interconnected networks in the synthesized scaffold. The mechanical test suggested that the GO-2500 scaffold had excellent mechanical strength, which was 7.41 ± 0.82 MPa with 25% shrink. What is more, GO-2500 could totally rebound within 1s, after compressed to 90% shrink. The rates of GO-2500 were 1587 ± 60 and 246 ± 10% according to the water uptake and retention data, respectively. Furthermore, the detoxification of GO-2500 to urea, creatinine, VB12, and β2-m were 67.59 ± 2.31, 39.67 ± 2.95, 31.51 ± 2.62, and 83.82 ± 7.76 mg/g, respectively. The resulting CS/GO-COOH scaffold held great potential for the detoxification of uremic toxins.
