Prolame produces anxiolytic- and antidepressant-like effects in middle-aged female rats with less uterotrophic effects than 17β-estradiol. Eur J Pharmacol 2024; 969:176454.

Abstract
Estrogen hormone replacement therapy (EHRT), improving women's life quality at menopause, reduces anxiety and depression symptoms associated with ovarian hormonal decline. However, its potential adverse effects, like thromboembolism and cancer risk, limit its use. Prolame is a synthetic 17β-amino estrogen with antithrombotic actions that exerts anxiolytic- and antidepressant-like effects on young adult ovariectomized female rats. It is unknown if prolame's effects may be observed in age and endocrine conditions emulating menopause. This study aimed to identify the antidepressant- and anxiolytic-like effects of prolame and E2 (used as a reference estrogen treatment) in middle-aged female rats coursing with irregular cycles, in two different conditions: ovariectomized or gonadally intact. Results were compared with those from young adult ovariectomized rats. Prolame (60 or 120 μg/kg), 17β-estradiol (E2, 40 or 80 μg/kg), or vehicle were chronically administered, and their effects were evaluated in the elevated plus-maze, defensive burying behavior test, open field test, and forced swimming test. Uterotrophic actions were estimated by uterine weight related to body weight. Prolame and E2 produced robust anxiolytic- and antidepressant-like effects in young adult ovariectomized rats, but these effects were absent in gonadally intact middle-aged rats. Interestingly, only prolame induced anxiolytic- and antidepressant-like effects in middle-aged ovariectomized rats. Uterotrophic effects of prolame were weaker than E2 effects, notably in middle-aged females. Altogether, present data support the notion that prolame has the potential to be considered an EHRT with relevant psychoactive actions and with apparently lower adverse-side effects, especially in middle-aged populations.

Abstract
Epidemiological and experimental data have indicated the beneficial and adverse effects
of estrogenic replacement therapy. In the present study, we explored the effect of
ethinylestradiol (EE) and 17β-estradiol (E2) on screening tests, prothrombin
time (PT) and activated partial thromboplastin time (APTT), as well as the activity of
coagulation factors (FVII, FX, FXI, and FXII) in male Wistar rats. Animals were injected
subcutaneously during three consecutive days with EE or E2 (1, 3, 10, and 30
mg/kg) and propylene glycol (0.3 ml; vehicle, V). EE produced significant increments
(P<0.05) on PT (8, 13, 15, and 10%) and APTT (32, 35, and 28%),
whereas E2 did not show any effect. EE diminished the activity of factors VII
(−10, −13, and −10%) and X (−10, −9, −15, and −14%; P<0.05), and
E2 (1 mg/kg) produced a modest increment (8%; P<0.05) on
FX only. E2 (10 mg/kg) showed a diminution of 9% (P<0.05),
while EE did not produce any response on factor XII. EE diminished (−15, −14, −19, and
−17%) but E2 augmented (10, 14, 24, and 24%) factor XI activity
(P<0.05). Our findings suggest that EE and E2 produce
different effects on coagulation and that EE seems to act across an inhibitory mechanism
of coagulation factor activity in the present experimental model.

Abstract
BACKGROUND The effect of endogenous hormone concentrations, specifically 17β-estradiol and progesterone, on fibrin network formation has not been established. OBJECTIVES It is essential to understand natural hormone mechanisms since these hormones are still present in circulation while hormonal contraceptives, which are associated with increased risk of venous thromboembolism, are used. METHODS Due to the fact that these hormones are known to increase hypercoagulability and the prothrombotic state scanning electron microscopy (SEM), atomic force microscopy (AFM), thromboelastography (TEG) and turbidimetry were employed to investigate the morphology, surface roughness, viscoelastic properties and formation and lysis of fibrin. RESULTS 17β-estradiol and progesterone showed hypercoagulable viscoelastic properties and decreased the diameter and surface roughness of fibrin while increasing dense matted deposit occurrence. Our results suggest that the additional burden of hormonal load, together with the presence of endogenous estrogen and progesterone, may result in a prothrombotic and hypercoagulable state in females with an inflammatory predisposition. CONCLUSION Our results are of clinical importance when considering hormones as either pathological agent or therapeutic intervention as will be assessed in future investigation.

Prog Neuropsychopharmacol Biol Psychiatry 2016; 64:102-8.

Abstract
Estrogens of clinical use produce consistent antidepressant- and anxiolytic-like effects in animal models of menopause. Regulation of the hypothalamic-pituitary-adrenal (HPA) or stress axis, has been proposed as a pathway through which estrogens improve affective-like behaviors. Anticoagulant 17β-aminoestrogens (17β-AEs) butolame and pentolame mimic some effects of estradiol (E2), i.e., on female rodent sexual behavior, with opposite actions on coagulation. However, their psychoactive actions have not been explored. On the basis of similitude with E2's effects, we hypothesized that these 17β-AEs would induce anxiolytic- and antidepressant-like effects, which would be reflected in a reduction of activity in the HPA axis. In ovariectomized female rats, chronic treatment with prolame (60 μg/kg), butolame (65 μg/kg) and pentolame (70 μg/kg) reduced anxiety-like behavior in the elevated plus maze (evidenced by an increase in time in open arms, E2 (40 μg/kg) +176%; prolame +201%; butolame, +237%; and pentolame +295%, in comparison to the control vehicle group 100%). Pentolame also decreased significantly anxiety-like behavior in the burying behavior test. Prolame and E2 produced a significantly antidepressant-like action, which was not induced by butolame and pentolame. Behavioral effects of 17β-AEs (and E2) on anxiety and depression did not follow the same pattern than corticosterone or E2 levels; they also were associated to changes in locomotor activity, evaluated by the open field test. These results constitute the first evidence of specific and selective actions of butolame and pentolame as anxiolytics for females with a hypoestrogenic condition. Results also confirm the potential of prolame as an antidepressant steroid with equivalent actions to E2. Psychoactive properties of 17β-AEs in combinations with reduced adverse effects on coagulation, suggest that 17β-AEs may be a good alternative replacement therapy for women with symptoms associated with menopause.

Abstract
Therapy with estrogens is frequently used in menopausal women and as hormonal contraception. Because of its thrombotic effects, long term estrogen administration used in hormonal replacement therapy (HRT) and contraception could represent a health hazard. In this regard, 17β-aminoestrogens such as aminoestrol, butolame and pentolame have shown promising HRT potential, because they have a weak agonist estrogenic action and antithrombotic activity. Additionally, estrogens play a protective role in airway smooth muscle, but the effect of 17β-aminoestrogens on the airway smooth muscle has not been tested yet. In guinea pig tracheal smooth muscle pentolame and butolame induced hyperresponsiveness to histamine (His), carbachol (Cch) and KCl. Interestingly, aminoestrol did not show this effect at the highest concentration studied, it even lowered the contraction induced by Cch. The hyperresponsiveness induced by pentolame to His was abolished by nifedipine. In single tracheal myocytes, KCl induced an increment in the intracellular Ca(2+) concentration [Ca(2+)]i, pentolame also showed an increase in [Ca(2+)]i and the addition of KCl in the plateau of this rise further significantly augmented the [Ca(2+)]i response. Additionally, in patch clamp experiments pentolame increased the L-type Ca(2+) currents. Thus, 17β-aminoestrogens such as pentolame and butolame, but not aminoestrol, activate L-type Ca(2+) channel to induced hyperresponsiveness to Cch, His and KCl in guinea pig tracheal smooth muscle. Due to its lack of effect on airways and to its anticoagulant characteristics, aminoestrol seems to be the best alternative in the HRT among the 17β-aminoestrogens studied.

Abstract
17β-amino-1,3,5(10)estratrien-3-ol (17βAE2), is the 17β-aminoestrogens prototype possessing anticoagulant activity, contrasting with the procoagulant effects of 17β-estradiol (17βE2). Its estrogenicity profile has not been reported, and it was evaluated by uterotrophic assay, estrogen receptor binding affinity and its ability to induce gene transcription of the human estrogen receptor (hER)α mediated in a Saccharomyces cerevisiae yeast expression system. Additionally, 17βAE2 and 17αAE2 were compared with 17βE2 in HeLa cells co-transfected with expression vectors for hERα or hERβ subtypes and for an estrogen-responsive reporter gene. Immature female CD1 mice and Wistar rats (21 days old) were treated for three days with 17βAE2 (10-5000 μg/kg), 17βE2 (0.001-1000 μg/kg) or vehicle (propylenglycol 10 ml/kg) and uterine weights were estimated. 17βAE2 increased uterine weight in a dose-dependent manner. The effective dose (ED)50 uterine weight values: 17βAE2=552 and 764 μg/kg (17βE2=4.8 and 16 μg/kg) and their relative uterotrophic potency were 0.86 and 2.1 (17βE2=100) in mice and rats, respectively. 17βAE2 competed with [(3)H]E2 for the estrogen receptor. The 17βAE2 relative binding affinities (RBAs) were: 0.074; Ki=2.2×10(-6)M (17βE2=100; Ki=1.6×10(-9)M); 0.029 and Ki=3.8×10(-6)M (17βE2=100; Ki=1.1×10(-9)M) for mice and rats uteri respectively. 17βAE2 activated hERα-mediated β-galactosidase transcription activity in the yeast system co-transfected with hERα gene. 17βAE2 effective concentration (EC)50=1.82 μM (17βE2=2.14 nM) with a relative potency of 0.12 (17βE2=100). These transactivation effects were abolished by the antagonist fulvestrant (ICI 182,780), similarly to 17βE2. 17βAE2 and 17αAE2 bind with low relative affinity to hERα and hERβ. Both induced hER-mediated reporter gene transactivation in a dose-response manner. The overall results provide evidence that 17βAE2 has a weak agonist estrogenic action greatly mediated through the hERβ and to a lesser extent the hERα at genomic level.

Abstract
Rodent ovariectomy is an experimental method to eliminate the main source of sexual
steroids. This work explored for the first time the ovariectomy temporal changes induced
in the hemostatic coagulation markers: prothrombin time (PT), activated partial
thromboplastin time (aPTT), thrombin time (TT), and fibrinogen concentration (FIB) along
with uterine weight on adult female CD1 mice and Wistar rats. Uterine weight (Uw) was
assessed before ovariectomy (control), and 1, 3, 5, 7, 9, 16, and 21 days after surgery.
PT, aPTT, TT and FIB were estimated the same days, using reported standard techniques.
Ovariectomy decreased Uw, since day 1; and from day 10 to 21 reached the lowest values for
both species. After day 1, mice hemostatic parameters changed (PT +10%,
P<0.05; aPTT +53%, P<0.05; TT −24%,
P<0.05; FIB +67%, P<0.05). Rats showed
significant changes only in TT and FIB (TT −13%, P<0.001; FIB +65%,
P<0.001). Neither mice PT, aPTT and TT, recovered control values
after 21 days. In the rats from day 5 to 16 aPTT diminished (18–23%,
P<0.05) recovering to control values on day 21, TT after 9 days and PT
on day 16. In both species, FIB returned to its control values after 9 days. Ovariectomy
differentially altered the PT hemostatic parameter of mice and rats indicating a
non-equivalence among both species behaviour for experimental studies of blood
coagulation.

Abstract
OBJECTIVES This work evaluated chronic treatment with 17β-oestradiol (E2) and 17β-aminoestrogen pentolame (AEP) on prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen concentration (FIB). Male (M) and ovariectomized (Ovx) Wistar rats were used to explore gender differences in the pharmacological response. MATERIALS AND METHODS Rats (n=12-18) were treated every third day during three months with E2 (1, 10, 100 μg/kg), AEP (1, 10, 100, 500 μg/kg) or vehicle (propylenglycol 1 ml/ kg). PT, aPTT, TT, and FIB were measured using standardized techniques. RESULTS Chronic treatment with E2 in male rats increased PT (4-7%; P<0.05), decreased aPTT (9%; 100 μg/kg; P<0.05) and decreased TT (5% at 100 μg/Kg; P<0.05). Chronic treatment with E2 in ovariectomized female rats decreased PT (3-4%; P<0.05), did not induce significant changes on aPTT and decreased TT in a dose dependent manner (12-27%; P<0.05). Chronic treatment with AEP in male rats did not alter PT, increased aPTT in a dose dependent manner (5-16%; P<0.05), and decreased TT (5%; 500 μg/Kg; P<0.05) while in female ovariectomized rats it decreased PT (5-9%; P<0.05), increased aPTT (8-13%; P<0.05) and decreased TT (6-13%; P<0.05). E2 and AEP decreased FIB in M and Ovx animals. Decreases in FIB by E2 were more pronounced in male (15-18% P<0.05) than in ovariectomized rats (10-14% P<0.05). E2 showed more potency than AEP, lowering FIB at 1 and 10 μg/kg doses. Both estrogens decreased FIB in ovariectomized animals (E2, 10-14%, P<0.05; AEP, 9% P<0.05) and were reverted by increasing dosage. CONCLUSIONS Gender influenced response to chronic treatment with E2 and AEP on hemostatic parameters. PT and aPTT were the most affected parameters, demonstrating non-equivalence in the pharmacological response of M and Ovx rats.
