Cells were pre-treated with rapamycin (Rapa, 1 μM) for 12 h, or KRIBB3 (KR, 0.5 μM) or chloroquine (CQ, 10 μM) for 2 h, followed by treatment with of palmitate (PA, 150 μM) for 24 h. Then the lipid in L02 cells was observed with Oil Red O (ORO) staining and ORO absorbance detection. Values are means ± SD (n = 3), *p b 0.05, versus matched controls.

Rapamycin aggravates the autophagic reaction induced by CVB3 infection. HeLa cells were treated with 10 nM rapamycin and chloroquine phosphate (CQ group) for 2 h. The cells were washed thrice and infected with CVB3. In the CVB3 group, HeLa cells were incubated with DMEM containing 10% FBS for 2 h and infected with CVB3. The sham group was incubated with DMEM containing 10% FBS. Two hours later, the medium was refreshed with DMEM containing 2% FBS. At 24 h.p.i., cells were collected for western blot analysis. The LC3-II/LC3-I ratio was increased in the CVB3 and rapamycin group (p<0.01), and p-mTOR was decreased in the CVB3 group (p<0.05) and rapamycin group (p<0.01) compared with the sham group. The changes in the LC3-II/LC3-I ratio and p-mTOR were more obvious in the Rap group compared with the CVB3 group (p<0.05). The LC3-II/LC3-I ratio and p62 was increased in the CQ group compared with the CVB3 group (p<0.05). *p<0.05, compared with the sham group; **p<0.01, compared with the sham group; #p<0.05, compared with the CVB3 group. CVB3, coxsackievirus B3; DMEM, Dulbecco's modified Eagle's medium; FBS, fetal bovine serum; h.p.i., hours post-inoculation; LC3, light chain 3; mTOR, mammalian target of rapamycin.

| In vitro |
Chloroquine is a chemotherapeutic agent for the clinical treatment of malaria. Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death. The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex. Chloroquine inhibits trophozoite hemoglobin degradation through increasing vacuolar pH and inhibiting the activity of vacuolar phospholipase, vacuolar proteases, and heme polymerase[1]. Chloroquine possesses definite antirheumatic properties. Chloroquine has immuno-modulatory effects, suppressing the production/release of tumour necrosis factor and interleukin 6. Moreover, Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best-studied effects are those against HIV replication[2]. Chloroquine can accumulate inside the macrophage phagolysosome by ion trapping where it exerts potent antifungal activity against Histoplasma capsulatum and Cryptococcus neoformans by distinct mechanisms. Chloroquine inhibits growth of H. capsulatum by pH-dependent iron deprivation, whereas it is directly toxic to C. neoformans[3]. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
