Application

Daptomycin has been studied as a potential therapy for Streptococcus pneumoniae infections. It has also been used to study the impact of sarA on daptomycin susceptibility of Staphylococcus aureus.

Biochem/physiol Actions

Daptomycin is a cyclic lipopeptide antibiotic. isolated from Streptomyces sp. It is effective against Gram-positive bacteria. It disrupts the plasma membrane causes rapid depolarization and inhibits the synthesis of protein, RNA and DNA. It is potent against Staphylococcus aureus infections, including MRSA (methicillin-resistant Staphylococcus aureus).

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

Impact of sarA on daptomycin susceptibility of Staphylococcus aureus biofilms in vivo.

Elizabeth C Weiss et al.

Antimicrobial agents and chemotherapy, 53(10), 4096-4102 (2009-08-05)

We used a murine model of catheter-associated biofilm formation to determine whether the mutation of the staphylococcal accessory regulator (sarA) has an impact on the susceptibility of established Staphylococcus aureus biofilms to treatment with daptomycin in vivo. The experiments were

A current perspective on daptomycin for the clinical microbiologist.

Romney M Humphries et al.

Clinical microbiology reviews, 26(4), 759-780 (2013-10-05)

Daptomycin is a lipopeptide antimicrobial with in vitro bactericidal activity against Gram-positive bacteria that was first approved for clinical use in 2004 in the United States. Since this time, significant data have emerged regarding the use of daptomycin for the

Iterative Chemical Engineering of Vancomycin Leads to Novel Vancomycin Analogs With a High in Vitro Therapeutic Index.

Nigam M Mishra et al.

Frontiers in microbiology, 9, 1175-1175 (2018-06-23)

Vancomycin is a glycopeptide antibiotic that inhibits transpeptidation during cell wall synthesis by binding to the D-Ala-D-Ala termini of lipid II. For long, it has been used as a last resort antibiotic. However, since the emergence of the first vancomycin-resistant

Comprehensive antibiotic-linked mutation assessment by resistance mutation sequencing (RM-seq).

Romain Guérillot et al.

Genome medicine, 10(1), 63-63 (2018-09-01)

Mutation acquisition is a major mechanism of bacterial antibiotic resistance that remains insufficiently characterised. Here we present RM-seq, a new amplicon-based deep sequencing workflow based on a molecular barcoding technique adapted from Low Error Amplicon sequencing (LEA-seq). RM-seq allows detection

Protective Action of Linear Polyethylenimine against Staphylococcus aureus Colonization and Exaggerated Inflammation in Vitro and in Vivo.

Venkatesh Mayandi et al.

ACS infectious diseases, 5(8), 1411-1422 (2019-05-18)

Increased evolution of multidrug resistant pathogens necessitates the development of multifunctional antimicrobials. There is a perceived need for developing new antimicrobials that can interfere with acute inflammation after bacterial infections. Here, we investigated the therapeutic potential of linear polyethylenimine (LPEI)
