Cefaclor is a well-absorbed orally active cephalosporin antibiotic. Cefaclor can specifically bind to specific for penicillin-binding protein 3 (PBP3). Cefaclor can be used for the research of depression and kinds of infections caused by bacteria, such as respiratory tract infections, bacterial bronchitis, pharyngitis and skin infections.

CHO	IC₅₀	8200 μM Compound: Cefaclor	TP_TRANSPORTER: inhibition of Gly-Sar uptake (Gly-Sar: 20 uM) in PEPT1-expressing CHO cells TP_TRANSPORTER: inhibition of Gly-Sar uptake (Gly-Sar: 20 uM) in PEPT1-expressing CHO cells	[PMID: 10052994]

In Vitro

Cefaclor (0-500 μg/mL, 12-24 h) shows obvious antibacterial activity against 556 Gram-positive and Gram-negative isolates. The MIC values of most strains are lower than 3.1 μg/mL, and the MIC value of Staph. aureus is 1 μg/mL in vitro^[4].
Cefaclor (60/500 μM, 30 min) is mainly transported by hPepT2 and hPepT1 in the MDCK stably transduced cell line overexpressing hOAT1、hPepT1 and hPepT2^[2].
Cefaclor (0.16 mg/mL, 30 min) can induce allergic reactions by directly activating basophils and mast cells^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cefaclor (200 mg/kg/day, p.o. once a day for 5 days) can cause intestinal flora imbalance in mice, as well as anxiety and depression-like behaviors in mice. These symptoms can be alleviated by Fluoxetine (HY-B0102) or vagotomy^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6J mice (male, 5 weeks old)^[1]
Dosage:

200 mg/kg/day, once a day for 5 days.
Administration:

p.o.
Result:

Significantly decreased serotonin levels in the hippocampus and BDNF in mice.
Cefaclor-induced gut dysbiosis caused anxiety and depression through the microbiota-gut-blood-brain and the microbiota-gut-vagus nerve-brain pathway.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
