ANTIMICROBIAL ACTIVITY OF LIPOPEPTIDES

The constantly growing number of multidrug-resistant bacterial strains prompts the search for alternative treatments. Synthetic peptides based on natural antimicrobial peptides, also known as antimicrobial lipopeptides, can become a promising group of “drugs” to fight multi-resistant bacteria. The present paper discusses the origins of synthetic lipopeptides, their classification and antimicro- bial properties.

Antifungal Activity and Physicochemical Properties of a Novel Antimicrobial Protein AMP-17 from Musca domestica

fluorocytosines are the most commonly used drugs for the treatment of fungal infections; however, all have certain toxicity and side effects, and drug-resistant strains are constantly emerging. (Bellmann and Smuszkiewicz 2017; Spitzer et al. 2017). Therefore, the development of new antifungal drugs is urgently needed for clinical anti-infection treatment. Antimicrobial peptides (AMPs), also known as host defense peptides, are biologically active molecules produced by various organisms as important components

The production, serologic evaluation, and epitope mapping of ten murine monoclonal Dombrock antibodies

embryonic kidney 293T cells expressing high levels of Doa or Dob. The MoAbs were tested serologically with untreated and enzymatically or chemically modified red blood cells (RBCs). Serologic inhibition studies were performed with synthetic peptides corresponding to Doa and Dob amino acid sequences. Pepscan epitope analysis was done on an array of immobilized tridecapeptides corresponding to the full-length polypeptide. All ten antibodies were serologically specific for Dombrock. Eight of the antibodies

CATHELICIDINS IN HUMANS AND ANIMALS

1. What are immune peptides Peptides of immunity – HDPs (Host Defense Peptides), form a complex of old, evolutionarily preserved effector molecules synthesized by the organisms of mammals (humans, animals – including marsupials and monotremes), birds, reptiles, amphibians, fish, insects and plants. Even microorganisms have not developed a defence mechanism against these substances along their evolutionary path, hence HDPs are often referred to as natural antibiotics [36, 56, 60, 87, 89, 93, 94

CHARACTERISTICS AND POTENTIAL APPLICATIONS OF CIRCULAR BACTERIOCINS

Bacteriocins are ribosomally synthesized peptides or proteins exerting anatagonistic activity toward organisms which are closely related to the producer strain. Circular bacteriocins are produced by Gram-positive bacteria, mainly lactic acid bacteria, and to a lesser extent by Bacillus, Clostridium and Staphylococcus genera. These bacteriocins are characterized by the head-to-tail cyclization of their backbone. The circular nature of these peptides makes them resistant to many proteolytic

Distribution of Cell Envelope Proteinases Genes among Polish Strains of Lactobacillus helveticus

Most of the lactic acid bacteria (LAB) are able to grow in milk mainly due to the activity of a complex and well-developed proteolytic system. Cell envelope-associated proteinases (CEPs) begin casein hydrolysis and allow for releasing the peptides, enclosed in the structure of native milk proteins that are essential for growth of Lactobacillus helveticus. The biodiversity of genes encoding CEPs among L. helveticus strains can have an effect on some technological parameters such as acid

Evaluation and comparison of three human monoclonal anti-S, two human polyclonal anti-S, and one murine anti-GPB

synthetic peptides. The anti-S gave different patterns of reactivity. Reactivity with sialidase-treated RBCs showed that MS-93, MS-95, Mab 148, and X1960 recognize sialic acid independent epitopes, whereas MS-94 and A1958 require sialic acid for optimal reactivity. MS-95 and X1960 were strongly reactive with TSEN+ RBCs and only Mab 148 agglutinated S- Dantu+ and S- St(a+) RBCs. MS-94 and Mab-148 agglutinated S+ RBCs treated with NaCIO. MS-93 was inhibited only by the 14-mer S-specific synthetic peptide

POSSIBILITIES OF PREVENTION AND TREATMENT OF HUMAN CYTOMEGALOVIRUS INFECTIONS INCLUDING NEW DRUGS AND COMPOUNDS WITH POTENTIAL APPLICATION

valylated cyclopropavir ester may have improved pharmacokinetic properties [7, 17, 29, 40]. Currently, phase 1 trials are being conducted to assess the safety and pharmacokinetics of cyclopropavir administered in healthy volunteers at various doses [4]. 3.4. Antiviral peptides It is believed that peptide drugs may be an alternative for the treatment of viral infections. So far, studies have been concerned with their mechanism of action against viruses causing respiratory infections [41], HBV [28] and

analysis confirmed the presence of plw structural gene encoding for plantacirin W in the selected L. plantarum strains. Moreover, we showed that the active peptides of Cys5-4 strains contrast effectively, in a bactericidal manner, the growth of food borne E. coli UTNEc1 and Salmonella UTNSm2, with about tree fold reduction of viable counts at the early stage of the target cell growth. The results indicated that the bacteriocin produced by selected native lactic acid bacteria strains has elevated

Antiepileptic drugs as a new therapeutic concept for the prevention of cognitive impairment and Alzheimer’s disease. Recent advances

Introduction. Excessive accumulation of amyloid-beta (A_) peptides in the brain results initially in mild cognitive impairment (MCI) and finally in Alzheimer’s disease (AD). Evidences from experimental and clinical studies show that pathological hyperexcitability of hippocampal neurons is a very early functional impairment observed in progressive memory dysfunctions. Therefore, antiepileptic drugs (AEDs) whose mechanism of action is aimed at inhibition of such neuronal hyperexcitability
