Genome-Based Mining of Carpatamides I-M and Their Candidate Biosynthetic Gene Cluster.

Chemically investigating the marine-derived 1268 led to the isolation of a new compound of carpatamide I (). Subsequent genomic analysis identified its candidate biosynthetic gene cluster of approximately 44 kb. In order to obtain more carpatamide derivatives, we conducted the upregulation of Ctd14, which is a positive regulator, and obtained improvement of carpatamide I and four new compounds of carpatamides J-M (-).

Rare primary colonic T cell lymphoma with curative resection by endoscopic submucosal dissection: A case report.

Primary gastrointestinal lymphoma mainly occurs in the stomach and small intestine, and the colon is less frequently involved, especially in females.

LDLR promotes autophagy-mediated cisplatin resistance in ovarian cancer associated with the PI3K/AKT/mTOR signaling pathway.

Autophagy is one of the underlying causes of resistance to many antitumor drugs, including cisplatin (DDP). The low-density lipoprotein receptor (LDLR) is a regulator of ovarian cancer (OC) progression. However, whether LDLR regulates DDP resistance in OC via autophagy-related pathways remains unclear.

Sleep disorders and non-sleep circadian disorders predict depression: A systematic review and meta-analysis of longitudinal studies.

Validation of efficacy and mechanism of Sanwei-Tanxiang powder in improving myocardial ischemia reperfusion injuries.

Sanwei-Tanxiang powder (SWTX), a traditional Mongolian and Tibetan medicine containing a cocktail of active molecules, relieves angina pectoris and improves recovery in patients with coronary heart disease (CHD). The pharmacological effect of SWTX on CHD was analyzed at a systemic point of view in our previous studies. The bioinformatics prediction showed that the PI3K/Akt/FoxO3a pathway was one of important pathways of SWTX on treatment of coronary heart disease.

The efficacy and safety of omega-3 fatty acids on depressive symptoms in perinatal women: a meta-analysis of randomized placebo-controlled trials.

To examine the efficacy and safety of omega-3 fatty acids (FA) monotherapy for perinatal depression (PND) compared with placebo. PubMed, Embase, PsycINFO, MEDLINE, Cochrane Library, and CINAHL were searched from inception up to November 2019.

Ansavaricin J, a New Heterocyclic Ring-Fused Streptovaricin from Gene stvP5-Deleted Mutant of Streptomyces spectabilis CCTCC M2017417.

A new ring-fused streptovaricin analogue, named ansavaricin J, was unprecedently isolated from the culture of the genetically modified strains ΔstvP5 which derived from Streptomyces spectabilis CCTCC M2017417. Its structure was elucidated via comprehensive spectroscopic analyses, including 1D- and 2D-NMR tests, and HR-ESI-MS data analysis. Notably, ansavaricin J and E represent the only two reported examples of heterocyclic ring-fused streptovaricins thus far, however, it only showed insignificant antibacterial activities against Staphylococcus aureus.

MicroRNA-9 promotes tumorigenesis and mediates sensitivity to cisplatin in primary epithelial ovarian cancer cells.

MicroRNAs play critical roles in regulating tumor occurrence and drug sensitivity in ovarian cancers. This study aimed to investigate the key members of MicroRNAs (miRNAs) involved in modulating tumor initiation and drug resistance in primary ovarian cancer cells. An in vitro assay based on tumor clonal formation was established to evaluate tumorigenicity and cisplatin sensitivity.

Novel second-harmonic-generation-active lead(II) phosphinate based on 2-carboxyethyl(phenyl)phosphinate ligand.

The hydrothermal reaction of PbCl(2) with the achiral 2-carboxyethyl(phenyl)phosphinate ligand (H(2)L) afforded a novel lead(II) phosphinate that contains two enantiomers as a racemic mixture, namely, [Pb(HL)(2)] (Λ- and Δ-1). Each enantiomer features a two-fold symmetrical chiral chain, in which the adjacent Pb(2+) ions are doubly bridged by pairs of HL(-) ligands. The uni-oriented stacking of such 1D chains by edge-to-face π···π interactions results in its crystallization in the chiral C2 space group.

Two polymorphs of (2-carboxyethyl)(phenyl)phosphinic acid.

Two polymorphs of (2-carboxyethyl)(phenyl)phosphinic acid, C(9)H(11)O(4)P, crystallize in the chiral P2(1)2(1)2(1) space group with similar unit-cell parameters. They feature an essentially similar hydrogen-bonding motif but differ slightly in their detailed geometric parameters. For both polymorphs, the unequivocal location of the hydroxy H atoms together with the expected differences in the P-O bond lengths establish unequivocally that both forms contain the S isomer; the protonated phosphinic acid and carboxy O atoms serve as hydrogen-bond donors, while the second phosphinic acid O atom acts as a double hydrogen-bond acceptor and the remaining carboxy O atom is not involved in hydrogen bonding.

Poly[bis-[μ(2)-(dimethyl-aza-nium-yl)methyl-enediphospho-nato]magnesium].

The title compound, [Mg(C(3)H(10)NO(6)P(2))(2)](n), synthesized by a hydro-thermal method, adopts a one-dimensional polymeric chain structure and is isotypic with the previously reported Cd complex based on the ligand N,N-dimethyl-amino-methane-1,1-diphospho-nic acid (H(4)L). The asymmetric unit contains one half Mg(2+) ion and one H(3)L(-) anion. The unique Mg(2+) ion lies on an inversion center and is octa-hedrally coordinated by O atoms from six phospho-nate groups of four different H(3)L(-) anions.

Octanuclear aluminum(III) and iron(III) phosphonate cages encapsulating two Na(I) ions.

Hydrothermal reactions of aluminum(III) nitrate or iron(III) nitrate with N,N-dimethylaminomethane-1,1-diphosphonic acid (H(4)L) and sodium hydroxide lead to two novel isostructural octanuclear metal phosphonate cages encapsulating two Na(I) ions, namely, [Al(8)Na(2)(HL)(2)(H(2)L)(10)(H(2)O)(6)] x 20 H(2)O (1) and [Fe(8)Na(2)(HL)(2)(H(2)L)(10)(H(2)O)(6)] x 22 H(2)O (2). The molecular structure of 1 can be viewed as a three-in-one cluster, in which a central zeolite D6R SBU lookalike aluminophosphonate cage is capped by two symmetry-related aluminophosphonate tetrahedral cages above and below and such a tetrahedral cage, being composed of four zeolite S6R SBU lookalike aluminophosphonate rings, further hexadentately traps one Na(+) ion in its cavity.
