Chlorophyllin Supplementation of Medicated or Unmedicated Swine Diets Impact on Fecal Escherichia coli and Enterococci. Animals (Basel) 2024; 14:1955. [PMID: 38998066 PMCID: PMC11240447 DOI: 10.3390/ani14131955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 06/12/2024] [Accepted: 06/26/2024] [Indexed: 07/14/2024] Open
Abstract
Considering that certain catabolic products of anaerobic chlorophyll degradation inhibit efflux pump activity, this study was conducted to test if feeding pigs a water-soluble chlorophyllin product could affect the antibiotic resistance profiles of select wild-type populations of fecal bacteria. Trial 1 evaluated the effects of chlorophyllin supplementation (300 mg/meal) on fecal E. coli and enterococcal populations in pigs fed twice daily diets supplemented without or with ASP 250 (containing chlortetracycline, sulfamethazine and penicillin at 100, 100 and 50 g/ton, respectively). Trial 2, conducted similarly, evaluated chlorophyllin supplementation in pigs fed diets supplemented with or without 100 g tylosin/ton. Each trial lasted 12 days, and fecal samples were collected and selectively cultured at 4-day intervals to enumerate the total numbers of E. coli and enterococci as well as populations of these bacteria phenotypically capable of growing in the presence of the fed antibiotics. Performance results from both studies revealed no adverse effect (p > 0.05) of chlorophyllin, antibiotic or their combined supplementation on average daily feed intake or average daily gain, although the daily fed intake tended to be lower (p = 0.053) for pigs fed diets supplemented with tylosin than those fed diets without tylosin. The results from trial 1 showed that the ASP 250-medicated diets, whether without or with chlorophyllin supplementation, supported higher (p < 0.05) fecal E. coli populations than the non-medicated diets. Enterococcal populations, however, were lower, albeit marginally and not necessarily significantly, in feces from pigs fed the ASP 250-medicated diet than those fed the non-medicated diet. Results from trial 2 likewise revealed an increase (p < 0.05) in E. coli and, to a lesser extent, enterococcal populations in feces collected from pigs fed the tylosin-medicated diet compared with those fed the non-medicated diet. Evidence indicated that the E. coli and enterococcal populations in trial 1 were generally insensitive to penicillin or chlortetracycline, as there were no differences between populations recovered without or with antibiotic selection. Conversely, a treatment x day of treatment interaction observed in trial 2 (p < 0.05) provided evidence, albeit slight, of an enrichment of tylosin-insensitive enterococci in feces from the pigs fed the tylosin-medicated but not the non-medicated diet. Under the conditions of the present study, it is unlikely that chlorophyllin-derived efflux pump inhibitors potentially present in the chlorophyllin-fed pigs were able to enhance the efficacy of the available antibiotics. However, further research specifically designed to optimize chlorophyll administration could potentially lead to practical applications for the swine industry.

Anti-adipogenic activities of pheophorbide a and pyropheophorbide a isolated from wild bitter gourd (Momordica charantia L. var. abbreviata Seringe) in vitro. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2022; 102:6771-6779. [PMID: 35638177 DOI: 10.1002/jsfa.12044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 05/14/2022] [Accepted: 05/30/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND The wild bitter gourd (WBG) is a commonly consumed vegetable in Asia that has antioxidant and hypoglycemic properties. The present study aimed to investigate the anti-adipogenic activities of isolated compounds from WBG on 8-day differentiated cultures of 3 T3-L1 adipocytes that were then stained with Oil Red O (ORO) or diamidino-2-phenylindole (DAPI). RESULTS ORO stains of the methanol extracts of de-seeded HM86 cultivar of WBG (WBG-M) and the ethyl acetate fractions (WBG-M-EA) showed anti-adipogenic activities against differentiated adipocytes. Two chlorophyll-degraded compounds, pheophorbide a (1) and pyropheophorbide a (2), were isolated from WBG-M-EA. Treatments with 1 (5, 10, and 20 μmol L-1 ) and 2 (2.5, 5, and 10 μmol L-1 ) showed dose-dependent reductions in lipid accumulations and reduced nuclear DAPI stains in differentiated 3 T3-L1 adipocytes. The concentrations for 50% inhibition against lipid accumulations of 1 and 2, respectively, were 16.05 and 7.04 μmol L-1 . Treatments with 1 and 2 showed enhanced lactate dehydrogenase release in the first 4-day cell mitotic clonal expansions during the differentiating cultural processes, although the effect was less on the non-differentiating cultural processes. Thus, 1 and 2 were more toxic to differentiating adipocytes than to non-differentiated pre-adipocytes, which partly resulted in anti-adipogenic activities with lowered lipid accumulations. CONCLUSION Both 1 and 2 showed anti-adipogenic activities in cell models. These chlorophyll-degraded compounds commonly exist in several vegetables during storage or edible seaweeds, which will provide resources for further investigations aiming to test anti-obesity in animal studies. © 2022 Society of Chemical Industry.

Abstract
With a continuous threat of antimicrobial resistance on human health worldwide, efforts for new alternatives are ongoing for the management of bacterial infectious diseases. Natural products of land and sea, being conceived to be having fewer side effects, pose themselves as a welcome relief. In this respect, we have taken a scaffolded approach to unearthing the almost unexplored chemical constituents of Malaysian red seaweed, Gracilaria edulis. Essentially, a preliminary evaluation of the ethyl acetate and acetone solvent extracts, among a series of six such, revealed potential antibacterial activity against six MDR species namely, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella enterica, methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pyogenes, and Bacillus subtilis. Detailed analyses of the inlying chemical constituents, through LC-MS and GC-MS chromatographic separation, revealed a library of metabolic compounds. These were led for further virtual screening against selected key role playing proteins in the virulence of the aforesaid bacteria. To this end, detailed predictive pharmacological analyses added up to reinforce Eplerenone as a natural alternative from the plethora of plausible bioactives. Our work adds the ongoing effort to re-discover and repurpose biochemical compounds to combat the antimicrobial resistance offered by the Gram-positive and the -negative bacterial species.

Abstract
Jangkanghwan (JKH) can delay weight loss in mice, promote weight gain during recovery, and reduce colonic shortening and colon weight. In addition, the murine disease activity index was controlled after treatment using JKH. It can reduce the content of pro-inflammatory factors in serum and expression in tissues, such as interleukin (IL)-6, IL-1β, tumor necrosis factor-α, interferon-γ, cyclooxygenase-2, and nuclear factor kappa-B; in contrast, the content and expression of IL-10 and the inhibitor of nuclear factor kappa-B kinase-α in the serum and tissues were increased. The mRNA expression of the colitis characteristic biomarker monocyte chemoattractant protein-1 and macrophage inflammatory protein-3α were reduced in colon tissues. Using next-generation sequencing technology, the Bacteroidetes phylum in the JKH group decreased, while the Firmicutes phylum increased, and the number of beneficial bacteria-Bifidobacteriaceae, Lactobacillaceae, and Akkermansiaceae-increased. PRACTICAL APPLICATIONS: JKH is a mixture of colonic healthy foods composed of Atractylodes macrocephala koidzumi, radish leaves, Viscum album var. coloratum, dried Zingiber officinale Roscoe, etc. According to UPLC-Q-TOF MS analysis, JKH consists mainly of 17 active substances, such as pheophorbide A, nabumetone alcohol, dehydrocostus lactone, plantamajoside, kaempferol 3, 7-dirhamnoside, quercetin 3-D-glucuronide, and viscumneoside III. We investigated the preventive effects of JKH on dextran sulfate sodium (DSS)-induced ulcerative colitis in a murine model and found that JKH can reduce the damage in mice caused by DSS treatment.

Chlorophyll and Chlorophyll Derivatives Interfere with Multi-Drug Resistant Cancer Cells and Bacteria. Molecules 2019; 24:molecules24162968.

Abstract
Multidrug resistance (MDR) causes challenging tasks in medicine. Human cancer cells, as well as microorganisms, can acquire multiresistance due to the up-regulation of efflux pumps (ABC transporters) and are difficult to treat. Here, we evaluated the effects of chlorophyll, the most abundant pigment on the globe, and its derivative, pheophytin, on cancer cells and methicillin-resistant Staphylococcus aureus (MRSA). We found that both substances have significant reversal effects on multidrug-resistant CEM/ADR5000 cells (RRpheophytin = 3.13, combination index (CI)pheophytin = 0.438; RRchlorophyll = 2.72, CIchlorophyll < 0.407), but not on drug-sensitive CCRF-CEM cells when used in combination with doxorubicin. This indicates that the porphyrins could interact with efflux pumps. Strong synergism was also observed in antimicrobial tests against MRSA when combining ethidium bromide with chlorophyll (FICI = 0.08). As there is a strong need for new drugs in order to reliably treat MDR cells, our research provides potential candidates for further investigation.

Abstract
We investigated whether pheophorbide A (PhA) could serve as a selective breast cancer resistance protein (BCRP) substrate (victim) to screen in vivo using fluorescent live animal imaging for transporter-mediated interactions with orally administered inhibitors (perpetrators), and whether that could be coupled with serum sampling to measure the systemic concentration of PhA with a fast-throughput in vitro fluorescent assay. PhA is a breakdown product of chlorophyll and is highly fluorescent in the near-infrared (NIR) spectrum. Whole-body NIR fluorescence was greater in the Bcrp KO compared with wild-type (WT) mice fed a regular diet containing chlorophyll and PhA, with fluorescence in WT mice confined to the intestine. PhA intestinal enterocyte fluorescence, after removing lumen contents, was greater in Bcrp knockout (KO) mice versus WT mice due to PhA enterocyte absorption and lack of PhA efflux by Bcrp. This difference was eliminated by maintaining the mice on an alfalfa (chlorophyll/PhA)-free diet. The area under the fluorescence ratio-time curve up to 6 hours (AUCFL 0-6 h) of orally administrated PhA was 3.5 times greater in the Bcrp KO mice compared with WT mice, and the PhA serum concentration was 50-fold higher in KO mice. Pretreatment with known BCRP inhibitors lapatinib, curcumin, elacridar, pantoprazole, and sorafenib, at clinically relevant doses, significantly increased PhA AUCFL 0-6 h by 2.4-, 2.3-, 2.2-, 1.5-, and 1.4-fold, respectively, whereas the area under PhA serum concentration-time curve calculated up to 6 hours (AUCSerum 0-6 h) increased by 13.8-, 7.8-, 5.2-, 2.02-, and 1.45-fold, respectively, and corresponded to their hierarchy as in vitro BCRP inhibitors. Our results demonstrate that live animal imaging using PhA can be used to identify BCRP inhibitors and to assess the potential for BCRP-mediated clinical drug-drug interactions.
