Abstract
An efficient method for synthesising NMDAR co-agonist Sunifiram (DM235), in addition to Sunifram-carbamate and anthranilamide hybrids, has been developed in high yields via protecting group-free stepwise unsymmetric diacylation of piperazine using N-acylbenzotiazole. Compounds 3f, 3d, and 3i exhibited promising nootropic activity by enhancing acetylecholine (ACh) release in A549 cell line. Moreover, the carbamate hybrid 3f was found to exhibit higher in vitro potency than donepezil with IC50 = 18 ± 0.2 nM, 29.9 ± 0.15 nM for 3f and donepezil, respectively. 3f was also found to effectively inhibit AChE activity in rat brain (AChE = 1.266 ng/mL) compared to tacrine (AChE = 1.137 ng/ml). An assessment of the ADMET properties revealed that compounds 3f, 3d, and 3i are drug-like and can penetrate blood-brain barrier. Findings presented here showcase highly potential cholinergic agents, with expected partial agonist activity towards glycine binding pocket of NMDAR which could lead to development and optimisation of novel nootropic drugs.

Abstract
AIMS Biological techniques can manage plant diseases safely and in environmentally friendly ways, but their efficacy needs improvement. It is of the utmost importance to search for powerful microbes for the effective control of plant diseases. METHODS AND RESULTS Unheated self-digestive solutions (SDS) that were heated at 100°C for 30 min(H-SDS) or stored for 12 months at room temperature (S-SDS) were prepared from Lysobacter enzymogenes LE16 broth culture to study their potential as biocontrol agents. This bacterium produced protease, phosphatase, lysozyme and siderophores in pure culture as well as 12 secondary metabolites including novel antibiotics lysobactin, WAP-8294A2 and mupirocin determined based on the antiSMASH 5.0.0 blast database. A poison plate assay revealed the antagonistic activities of SDS, H-SDS and S-SDS against an animal pathogenic bacterium Staphylococcus aureus, a phytopathogenic bacterium Pseudomonas syringae pv. tabaci, and numerous plant pathogenic fungi and oomycetes, including Colletotrichum gloeosporioides, Penicillium italicum, Alternaria alternate, Rhizoctonia solani, Didymella bryoniae, Sclerotinia sclerotiorum, Phytophthora nicotianae and Phytophthora capsici. The greenhouse experiment showed that SDS was highly effective in controlling pepper blight disease, which is caused by P. capsici. Compared with only pathogen inoculation, the application of SDS to the soil in preventive or curative treatments significantly reduced the disease incidence and index with relatively high control efficacy of 86·2-93·1%. CONCLUSIONS SDS enriched lytic enzymes, siderophores and antibiotics, has a wide antimicrobial spectrum, and shows potential as a new, safe and effective biocontrol agent against plant diseases. SIGNIFICANCE AND IMPACT OF THE STUDY Autolysates of the new biocontrol bacterium L. enzymogenes LE16 demonstrated the potential for industrial production and commercial use as a promising biocontrol agent in agriculture.

Front Cell Neurosci 2019; 13:176. [PMID: 31133807 PMCID: PMC6517548 DOI: 10.3389/fncel.2019.00176] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Accepted: 04/12/2019] [Indexed: 11/13/2022] Open
Abstract
3-iodothyroacetic acid (TA1), an end metabolite of thyroid hormone, has been shown to produce behavioral effects in mice that are dependent on brain histamine. We now aim to verify whether pharmacologically administered TA1 has brain bioavailability and is able to induce histamine-dependent antidepressant-like behaviors. TA1 brain, liver and plasma levels were measured by LC/MS-MS in male CD1 mice, sacrificed 15 min after receiving a high TA1 dose (330 μgkg-1). The hypothalamic mTOR/AKT/GSK-β cascade activation was evaluated in mice treated with 0.4, 1.32, 4 μgkg-1 TA1 by Western-blot. Mast cells were visualized by immuno-histochemistry in brain slices obtained from mice treated with 4 μgkg-1 TA1. Histamine release triggered by TA1 (20-1000 nM) was also evaluated in mouse peritoneal mast cells. After receiving TA1 (1.32, 4 or 11 μgkg-1; i.p.) CD1 male mice were subjected to the forced swim (FST) and the tail suspension tests (TST). Spontaneous locomotor and exploratory activities, motor incoordination, and anxiolytic or anxiogenic effects, were evaluated. Parallel behavioral tests were also carried out in mice that, prior to receiving TA1, were pre-treated with pyrilamine (10 mgkg-1; PYR) or zolantidine (5 mgkg-1; ZOL), histamine type 1 and type 2 receptor antagonists, respectively, or with p-chloro-phenylalanine (100 mgkg-1; PCPA), an inhibitor of serotonin synthesis. TA1 given i.p. to mice rapidly distributes in the brain, activates the hypothalamic mTOR/AKT and GSK-3β cascade and triggers mast cells degranulation. Furthermore, TA1 induces antidepressant effects and stimulates locomotion with a mechanism that appears to depend on the histaminergic system. TA1 antidepressant effect depends on brain histamine, thus highlighting a relationship between the immune system, brain inflammation and the thyroid.

Abstract
Lysobacter are considered "peptide specialists". However, many of the nonribosomal peptide synthetase genes are silent. Three new compounds were identified from L. enzymogenes upon activating the six-module-containing led cluster by the strong promoter PHSAF. Although ledD was the first gene under PHSAF control, the second gene ledE was expressed the highest. Targeted gene inactivation showed that the two-module LedE and the one-module LedF were selectively used in pyrrolopyrazine biosynthesis, revealing a module/domain portable mechanism.

Abstract
The piperazine ring of the potent nootropic drug DM235 has been decorated with H-bond donor and acceptor groups (CH2OH, CH2OMe, CH2OCOMe, COOEt); the aim was to insert new functional groups, suitable for further chemical manipulation. The influence of these modifications on nootropic activity was assessed by means of the mouse passive avoidance test; some of the newly synthesized molecules (alcohol 7b, acetate 8b and ester 10d) showed interesting in vivo potency. This makes it possible to use these functional groups for adding other residues, in order to increase molecular diversity, or for anchoring a biotin group, to obtain compounds useful to capture the biological target. Moreover, the new compounds will improve our knowledge of structure activity relationships of this family of drugs.

Abstract
This paper is a review of the work of my former academic group of research in the past 15 years, in the field of cognition enhancers (also called nootropics) that identified two very potent molecules: Unifiram and Sunifiram that for a variety of reasons were not protected by a patent. Some 12 years after their disclosure (2000) I casually found that on the web, there were dozens of sites offering Unifiram and Sunifiram as drugs that improve cognition in healthy individuals even if only few preclinical studies were done and their long-term toxicity was unknown.
