Discovery and Mechanistic Analysis of Structurally Diverse Inhibitors of Acetyltransferase Eis among FDA-Approved Drugs.

Over one and a half million people die of tuberculosis (TB) each year. Multidrug-resistant TB infections are especially dangerous, and new drugs are needed to combat them. The high cost and complexity of drug development make repositioning of drugs that are already in clinical use for other indications a potentially time- and money-saving avenue.

Advancements in Oncoproteomics Technologies: Treading toward Translation into Clinical Practice.

Proteomics continues to forge significant strides in the discovery of essential biological processes, uncovering valuable information on the identity, global protein abundance, protein modifications, proteoform levels, and signal transduction pathways. Cancer is a complicated and heterogeneous disease, and the onset and progression involve multiple dysregulated proteoforms and their downstream signaling pathways. These are modulated by various factors such as molecular, genetic, tissue, cellular, ethnic/racial, socioeconomic status, environmental, and demographic differences that vary with time.

Isolated Right Internal Jugular Vein Thrombosis: a Rare Complication of Acute Pancreatitis - a Case Report.

Vascular complications particularly splanchnic vein thrombosis can occur in acute as well as chronic pancreatitis, but extra-splanchnic thrombosis occurs rarely. We report a rare case of acute pancreatitis complicated by isolated internal jugular vein thrombosis. A 26-year-old Indian woman presented with complaints of severe epigastric pain radiating to the back, vomiting, and abdominal distension.

Discovery of substituted benzyloxy-benzylamine inhibitors of acetyltransferase Eis and their anti-mycobacterial activity.

A clinically significant mechanism of tuberculosis resistance to the aminoglycoside kanamycin (KAN) is its acetylation catalyzed by upregulated Mycobacterium tuberculosis (Mtb) acetyltransferase Eis. In search for inhibitors of Eis, we discovered an inhibitor with a substituted benzyloxy-benzylamine scaffold. A structure-activity relationship study of 38 compounds in this structural family yielded highly potent (IC ∼ 1 μM) Eis inhibitors, which did not inhibit other acetyltransferases.

A Role for Basigin in Toxoplasma gondii Infection.

The role of specific host cell surface receptors during Toxoplasma gondii invasion of host cells is poorly defined. Here, we interrogated the role of the well-known malarial invasion receptor, basigin, in T. gondii infection of astrocytes.

An insight on microbial degradation of benzo[a]pyrene: current status and advances in research.

Benzo[a]pyrene (BaP) is a high molecular weight polycyclic aromatic hydrocarbon produced as a result of incomplete combustion of organic substances. Over the years, the release of BaP in the atmosphere has increased rapidly, risking human lives. BaP can form bonds with DNA leading to the formation of DNA adducts thereby causing cancer.

Biotechnological tools to elucidate the mechanism of pesticide degradation in the environment.

Pesticides are widely used in agriculture, households, and industries; however, they have caused severe negative effects on the environment and human health. To clean up pesticide contaminated sites, various technological strategies, i.e.

Structure-based design of haloperidol analogues as inhibitors of acetyltransferase Eis from to overcome kanamycin resistance.

Tuberculosis (TB), caused by (), is a deadly bacterial disease. Drug-resistant strains of make eradication of TB a daunting task. Overexpression of the enhanced intracellular survival (Eis) protein by confers resistance to the second-line antibiotic kanamycin (KAN).

Development of Single-Stranded DNA Bisintercalating Inhibitors of Primase DnaG as Antibiotics.

Many essential enzymes in bacteria remain promising potential targets of antibacterial agents. In this study, we discovered that dequalinium, a topical antibacterial agent, is an inhibitor of Staphylococcus aureus primase DnaG (SaDnaG) with low-micromolar minimum inhibitory concentrations against several S. aureus strains, including methicillin-resistant bacteria.

Structure-Guided Optimization of Inhibitors of Acetyltransferase Eis from .

The enhanced intracellular survival (Eis) protein of () is a versatile acetyltransferase that multiacetylates aminoglycoside antibiotics abolishing their binding to the bacterial ribosome. When overexpressed as a result of promoter mutations, Eis causes drug resistance. In an attempt to overcome the Eis-mediated kanamycin resistance of , we designed and optimized structurally unique thieno[2,3-]pyrimidine Eis inhibitors toward effective kanamycin adjuvant combination therapy.

Probing the Robustness of Inhibitors of Tuberculosis Aminoglycoside Resistance Enzyme Eis by Mutagenesis.

Each year, millions of people worldwide contract tuberculosis (TB), the deadliest infection. The spread of infections with drug-resistant strains of () that are refractory to treatment poses a major global challenge. A major cause of resistance to antitubercular drugs of last resort, aminoglycosides, is overexpression of the Eis (enhanced intracellular survival) enzyme of , which inactivates aminoglycosides by acetylating them.

Active site plasticity enables metal-dependent tuning of Cas5d nuclease activity in CRISPR-Cas type I-C system.

Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) in association with CRISPR-associated (Cas) proteins constitutes a formidable defense system against mobile genetic elements in prokaryotes. In type I-C, the ribonucleoprotein surveillance complex comprises only three Cas proteins, namely, Cas5d, Csd1 and Csd2. Unlike type I-E that uses Cse3/CasE for metal-independent CRISPR RNA maturation, type I-C that lacks this deputes Cas5d to process the pre-crRNA.

In silico engineering of aggregation-prone recombinant proteins for substrate recognition by the chaperonin GroEL.

Background: Molecular chaperones appear to have been evolved to facilitate protein folding in the cell through entrapment of folding intermediates on the interior of a large cavity formed between GroEL and its co-chaperonin GroES. They bind newly synthesized or non-native polypeptides through hydrophobic interactions and prevent their aggregation. Some proteins do not interact with GroEL, hence even though they are aggregation prone, cannot be assisted by GroEL for their folding.

Insight into the enzyme-inhibitor interactions of the first experimentally determined human aromatase.

Aromatase is an important pharmacological target in the anti-cancer therapy as the intratumoral aromatase is the source of local estrogen production in breast cancer tissues. Suppression of estrogen biosynthesis by aromatase inhibition represents an effective approach for the treatment of hormone-sensitive breast cancer. Because of the membrane-bound character and heme-binding instability, no crystal structure of aromatase was reported for a long time, until recently when crystal structure of human placental aromatase cytochrome P450 in complex with androstenedione was deposited in PDB.

Inhibition of the NEMO/IKKβ association complex formation, a novel mechanism associated with the NF-κB activation suppression by Withania somnifera's key metabolite withaferin A.

Background: Nuclear Factor kappa B (NF-κB) is a transcription factor involved in the regulation of cell signaling responses and is a key regulator of cellular processes involved in the immune response, differentiation, cell proliferation, and apoptosis. The constitutive activation of NF-κB contributes to multiple cellular outcomes and pathophysiological conditions such as rheumatoid arthritis, asthma, inflammatory bowel disease, AIDS and cancer. Thus there lies a huge therapeutic potential beneath inhibition of NF-κB signalling pathway for reducing these chronic ailments.
