Protocol

Cell experiment [1]:

Cell lines

Mouse spermatozoa

Preparation Method

Mouse spermatozoa were incubated with various concentrations (0.001-100 μM) of steroids (estrogen and progesterone) and heparin for 15 or 30 min, and then capacitation and AR were assessed using chlortetracycline.

Reaction Conditions

0.001-100 μM; 15 or 30 min

Applications

Steroids (estrogen and progesterone) and heparin studied effectively alter capacitation and/or AR in mouse spermatozoa with different manner.

Animal experiment [2]:

Animal models

Four- to six-week-old Athymic BALB/c-nu/nu female nude mice (14-18 g)

Preparation Method

According to body weight and tumor size, the animals were divided into four experimental groups of five mice each: groups A, B, C, and D, respectively, received through the tail vein injections of 100 µL of saline as control (Group A, n=5), heparin (10 mg/kg, Group B, n=5), DOC-heparin VI (5 mg/kg, Group C, n=5), and DOC-heparin VI (10 mg/kg, Group D, n=5). Each drug was administered twice a week for four weeks after tumor inoculation.

Dosage form

10 mg/kg; i.v.

Applications

Larger antitumor effects of the DOC-heparin VI (8.5 mol of DOC coupled with 1.0 mol heparin) were achieved in animal studies, compared to heparin alone.

Background

Heparin sodium, as as anti-coagulants, belongs to a class of glucans, which can interact with a variety of proteins to produce a variety of biological activities.[1][2] Heparin sodium is routinely use for preventing the deep venous thrombosis in medical and surgical patients[5].

In vitro experiment it demonstrated that SARS-CoV-2 spike protein binds with a much higher affinity to heparin with K D of 55 nM compared to the RBD with K D of 1 μM alone. And heparin has no effect on angiotensin-converting enzyme 2 binding or proteolytic processing of the spike.[6] Moreover, heparin can inhibit the proteolytic activity of Mpro with an inhibition constant Ki of 6.9 nM and a half maximal inhibitory concentrations (IC50) of 7.8 ± 2.6 nM. [7].

In vivo clinical study it shown that treatment with continuous heparin sodium 12 500 U throughout 24 hours with intravenous pump for 5 days in heparin sodium group patients, and with low molecular weight heparin sodium (LMWHS) patients were given LMWHS 2 500 U subcutaneously, twice a day for 5 days, incidence of bleeding during treatment in LMWHS group was remarkably lower than that in heparin sodium group. Moreover, the platelet count in both LMWHS group and heparin sodium group was markedly increased compared with that before treatment; activated partial thromboplastin time also in heparin sodium group was significantly prolonged compared with that before treatment.[3] In the clinical test, there is no obvious difference in the duration of catheter patency or incidence of phlebitis was observed between the adult patients received 1 mL of a heparin sodium 100 units/mL flush solution and adult patients received a 0.9% sodium chloride flush solution by intermittent intravenous devices were randomly assigned.[4] In the clinical trail, treatment with low-dose heparin, patients with diabetes mellitus or chronic renal insufficiency are especially predisposed to hyperkalemia.[5].
